The Mastrumoto 4000 achievement list is basically a checklist of holes. I'm tracking unlocks like some degenerate accountant. Anal entry, double stuff, oral finish, the usual. But the game doesn't give you a clean path. You fumble through a basement POV, clicking on a brunette who's already bent over some eBay fuck-machine that looks like a repurposed engine block. The 3D models have that unpolished CG sheen, like someone learned Blender last Tuesday and immediately decided to make porn. It's perfect for this. A polished look would ruin the grimy basement vibe.

The rough sex tag isn't lying. There's no gentle lead-up. One moment you're positioning a sextoy attachment, the next the machine is jackhammering and Megan's mascara is a lost cause. The cumshot mechanics are weirdly specific. You can trigger them early, which I did by accident, and the scene just... continues? Like the machine doesn't care about your timing. It's a machine. That's probably the point. I wish the double penetration sequence had more feedback. You just sort of assume it's happening based on the angle. But then she makes this choked sound and you know. You just know.

I spent ten minutes trying to unlock a specific oral scene that I'm still not sure exists. The series tag suggests there's more of this somewhere, other subway fucker chapters maybe. This one feels like a middle child. The basement setting gets stale fast. Same concrete walls, same harsh lighting. But that's also why it works. It's not trying to be anything else. Just a room, a machine, and a brunette with no survival instincts. The POV never breaks. You're James, you're a creep with a magical sex robot, and you're going to watch it do all the work. Achievement popped for double penetration. Still missing the one for... something. Back to the basement.

The loading screen is a mess, honestly. It’s got that flash game energy where you just know someone cobbled it together in a basement, and the "bonus heroes" are just... there. Link is standing next to a furry version of Princess Peach and nobody questions it. I clicked on Krystal first because, well, she's the title, right? The whole thing is just her getting railed by a parade of monsters. There’s no plot to speak of, just a series of loops where a plant thing with too many tentacles finds every hole and then some. The cumshot animations are absurd, like someone turned a physics slider all the way up. It’s gross. I replayed that part three times.

The rough sex tag isn't kidding. There’s a moment with a lizard creature where the animation glitches and her spine bends in a way that made me wince, but also I couldn't look away. The sound design is basically just wet slaps and a looping moan that starts to sound like a broken alarm after a minute. I wish there was a way to skip to specific acts, but the interface is this clunky wheel of positions that never quite clicks where you want it to. And why is Peach even here? Her blowjob scene is just a reskin of Krystal's with a crown badly pasted on her head. It’s lazy, but it’s also the funniest thing in the game.

The furry stuff is front and center, obviously. Krystal’s design is actually the most polished part, which makes sense given the source material. The new tweaks they mention in the description? I couldn't find them. Maybe the cum puddles are slightly more reflective? I spent ten minutes trying to get Link to do something other than stand there with his sword out, but he’s just a statue. A voyeur. It’s a disjointed fever dream where the only goal is to see how many impossible positions a blue fox can get stuffed into. My browser crashed once and I didn't even care. Just refreshed and went right back to the lizard scene. The whole thing feels like a sticky, unapologetic sketchbook of bad ideas that somehow works because it doesn't pretend to be anything else.

The whole thing feels like someone’s first Flash project they abandoned halfway through, and I mean that as a weird compliment. Evangelyne from Wakfu just stands there, this flat cutout with that one expression, while you poke at her with a cursor that feels slightly drunk. The minigame is basically a rhythm thing but not really. You click, drag, whatever, and the animations trigger in these jerky little bursts. It’s rough sex in the most literal sense, the transitions are missing frames and her body snaps into positions like a doll with loose joints.

The submissive angle is there but it’s so barebones it circles back to being hot. You’re not managing meters or reading dialogue trees. You just… do things. And she reacts with these canned moans that loop awkwardly if you mess up the timing. There’s a moment where you can pull her hair and the sprite just stretches weirdly, like the artist forgot to draw an in-between frame. I laughed, then immediately went back to it. The hard sex scenes have zero buildup, it’s just straight to penetration with the sound of wet slapping that’s mixed way too loud. My phone’s speaker crackled at one point. Had to scramble for the volume button because I forgot I wasn’t using headphones. Classic solo play panic.

The Princess Peach xxx tag is misleading, she’s not here, it’s just Evangelyne in what I guess is a similar body type. Don’t go in expecting crossover fan service. The whole thing runs in a browser tab and crashed once when I tried to refresh. Lost my progress, which was just getting her top off, but still. For a soloid game it’s exactly what you’d expect, a quick, messy, unpolished fuck simulator that doesn’t pretend to be more. The lack of polish is the point. Or maybe it’s not and I’m just making excuses. Either way, I finished what I started.

Janky as hell and proud of it, Tentacles Thrive drops you into this messy, half-baked world where nothing quite works right and somehow that's the whole vibe. Sex scenes hit with that rough, unpolished animation style, tentacles wrapping around bodies in this frantic, almost desperate way, pantyhose tearing and fluids going everywhere. The interspecies stuff gets explicit fast, no buildup sometimes, just straight to hard pounding with creatures that look like they were sketched on a napkin during lunch.

Dubois bonding events caught me off guard. Actually spent way too long on those, clicking through dialogue that's barely coherent while the real-time battles chug along in the background. The Lv and RP animations, the little pulsing bars they added in v2.10, like someone said "hey this needs more juice" and just threw in flashy UI stuff instead of fixing the core systems still marked under development. Strategic battles could be fun if the pacing wasn't so weird, one moment you're managing some resource, halfway through a thought about reviving the Humana race, then bam, you're in a fight, then the game just stops at the world map like hitting a wall.

Knowledge sections in the Diary, okay sure, but why do I care about encyclopedia entries when the whole thing feels like it's held together with tape? That ending showcase preview, showing off progress like some kind of promise. Species creation mechanic, breeding new tentacles through mate combinations, fucking to unlock new forms, oral scenes that don't pull punches. Lilith's heart stealing subplot buried somewhere between the rough sex loops and managing whatever the Humana race is supposed to be. Thing is I kept clicking, kept coming back to this broken, horny mess, and that probably says something about me more than the game.

I downloaded this mess on a whim after getting stood up. again. third time this month. the download bar crawled and I just sat there thinking about how Lilith is probably gonna reject me in the game too. because that's my life. at least the download finished.

the first thing that hit me was the voice clips. three new ones apparently. one of them is this elf chick making sounds that made me forget my own name for a second. I replayed that one clip like fifteen times. the art looks like someone sketched it on a napkin during a boring meeting but honestly? the roughness kinda works when tentacles are involved. it makes everything feel dirtier. more desperate. there's this tentacle encyclopedia now and let me tell you my brain chemistry altered when I read the lore for the starting species. I can't explain why I care so much about the biology of fuck-tentacles but here we are.

the rest function is fully implemented which is nice because apparently the world map is where this version cuts off. right when things were getting interesting. the map function is just there. taunting me. six new enemy territories and I can't touch any of them. I spent way too long building my army inventory. you can hold any amount of units now. I had this whole strategy planned. scouting reports came back. intelligence gathered. I was ready to invade and then. nothing. the birth event is in there but without graphics so it's just text describing the thing. feels like getting edged for six hours and then the person just leaves. which I guess is also my life.

oh and you can steal Lilith's heart apparently. I haven't managed it. shocking. the real-time battles are actually decent though. I got my ass handed to me because I was too busy reading diary entries that are half finished. the whole game feels half finished. kinda like my last relationship. the tentacle sex is hot in a "I need therapy" way and the strategic layer made me forget I was supposed to be crying into my pillow tonight.

Maria’s back arches like she’s been waiting for this all day. The animation loops are simple, almost crude, but there’s something about the way her hips twitch when the thrust lands that makes my mouth dry. Sound design is doing the heavy lifting here. That wet, rhythmic slap isn’t trying to be polite. It’s messy and close, like someone forgot to close the mic, and honestly that’s what keeps me from clicking away. The music is just a low drone, barely there, so all you hear is skin and those little gasps she makes. Her voice cracks on a moan and I actually leaned closer to the screen. Stupid, I know.

The visual style is deliberately rough, almost like a sketch that got colored in too fast. Her tits bounce with a weird delay, like the physics engine is drunk, and I spent way too long fixating on that. It’s not realistic. It’s better. It’s that exaggerated anime logic where a body moves in ways that only exist in a horny brain. The lack of polish isn’t a bug, it’s the whole point. You see the seams in the animation, the way a frame stutters right before she clenches down, and it makes the whole thing feel more private. Like finding a corrupted file you weren’t supposed to see. I wish the camera would stop drifting to that one weird angle above her head though. Nobody wants to stare at a scalp during a rough scene. It pulls me out.

Then the pace shifts. It doesn’t build up, it just slams into a faster rhythm without warning. Her expression goes slack, mouth hanging open, and the sound cuts to just heavy breathing. No more music. No more wet noise. Just air. It’s jarring in a way that sticks to your skin. I closed the tab and opened it again five minutes later. I don’t know what that says about me. The loop is short, maybe too short, but that’s the thing. It doesn’t need to be long. It just needs to hit that one note perfectly. And it does. Until it doesn’t. The ending is just. A stop. No climax animation, no final shudder. She just freezes mid motion and the audio loops a breathy sigh forever. I sat there waiting for a finish that never comes. Maybe that’s the joke. Maybe I’m the one who’s supposed to finish.

Third one in this series and it's basically the same deal, which is fine if you're here for it. You get this guy with a camera, he's got that look like he just walked off a construction site and forgot his shirt. The girl is on all fours, completely naked, that specific pale teen body type they always use. The whole thing is framed like someone's amateur footage, shaky and too close, which I guess is the point but sometimes you just want to see what's happening without the camera wobbling into a wall texture.

There's this one moment where he grabs her hips and the animation loops in a way that's almost hypnotic. The sound is mostly wet slapping and her breathing, no music, nothing to distract from the mechanical repetition of the act. You can see the exact second the internal switch flips from "rough sex" to "we're definitely trying to get you pregnant here" because the pace changes, becomes more deliberate. The cumshot is ridiculous, like an entire water balloon's worth, and then the game just... sits there. Shows you the aftermath. That's the pregnancy tag in action I suppose, the implied result just hanging in the air.

The achievements for this one are straightforward. Do the thing, watch the thing, unlock the next variation. I spent way too long trying to figure out if camera angle changed anything. It doesn't. The dude's balls are distractingly large, like two g*** in a sock, and I couldn't stop noticing how they clip through her thigh in the close up shots. That's the kind of detail that sticks with you. Not the rough sex or the breeding focus, but the physics glitch on his sack. Typical.

The whole premise is a pizza delivery guy on a rocket scooter, but the pizza is basically a macguffin. You fly up and down this endless vertical street, dodging birds and clouds or whatever, and every few seconds a new apartment window slides open with a woman inside. Big tits, milf energy, the works. You stop, you deliver, and then the screen cuts to a hard sex scene. Rough, fast, no romance. It's like someone took the concept of Papers, Please but replaced all the tension with tits and called it a day.

The controls are weirdly floaty. You hold to go up, release to drop, and the scooter has this delayed momentum that makes you feel like you're piloting a drunk bumblebee. I clipped a pigeon at least six times. But the game doesn't punish you much, it just resets you a few meters back. The real reward is the animation loop after each delivery. The women all have that same slightly off model, like a bootleg Honey Select render from 2017, but the motion is smooth enough. There's no dialogue, no story, just grunts and the occasional "more" text bubble.

One thing I wish existed: a way to skip the flying part entirely. After the fifth delivery you've seen every obstacle pattern. The sex scenes vary a little, some are on a bed, one is against a window, but the pacing is identical. You can't fail the sex, you just watch. It's less of a game and more of a fap button with extra steps.

The milf tag is doing a lot of heavy lifting. Most of the women look late 30s to 40s, which is fine if that's your thing. The delivery boy never speaks, which is probably for the best. I forgot what I was complaining about. The pizza never gets delivered, by the way. You just hold it the whole time. That bothered me more than it should.

The loading screen is just a black void with two furniture options floating there like some kind of IKEA catalog from hell. Table or sofa. That's it. No story, no characters, no buildup. Just pick where you wanna fuck and get on with it. I chose the sofa first because I'm not a complete degenerate, and suddenly there's this big-titted anime girl bent over the armrest with her ass in the air. The art is rough, like someone drew it during a lunch break and never went back to clean up the lines. Her tits clip through the cushion when the animation loops. It's so janky that I laughed out loud, which I don't think was the intended reaction.

The position menu is where things get weirdly specific. Doggy style, sure. Cowgirl, fine. But then there's this option where she's somehow using the armrest as a fulcrum while doing a handstand? Her spine doesn't work like that. Nobody's spine works like that. The blowjob animation on the table setting has her head bobbing at this mechanical rhythm that reminds me of those drinking bird toys, and I couldn't unsee it. The sound effects are just two stock clips on repeat, a wet slapping noise and a moan that cuts off mid-breath every single time. After three minutes it loops so perfectly you start hearing phantom patterns in it like some kind of auditory pareidolia.

The humor tag is doing heavy lifting here because I genuinely can't tell if the jank is intentional or not. There's a moment during the table scene where you switch positions and her entire model teleports three feet to the left before snapping back. I rewound it four times. The furniture itself has this weird prominence, like the sofa and table are the real main characters and the sex is just happening around them. I spent way too long zooming in on the wood grain texture of the table, which is surprisingly detailed compared to everything else. Someone on the dev team really cared about that table. The big boobs tag is accurate at least, they move with this water balloon physics that defies gravity in ways that would make a physicist cry. Not complaining though. I wish there was a chair option. Why only table and sofa? What about ottomans? Missed opportunity.
