HeartProblems looks like one of those games you open just to “check it for five minutes” and then suddenly you’re clicking through scenes like a horny raccoon searching in the trash. On the surface it’s the usual porn VN setup: young guy, dead parents, moves in with uncle, house full of women that absolutely should not be as hot as they are. Milf energy in the kitchen, stacked bodies, tight clothes, that kind of slow-burn teasing where nothing “really” happens at first but your brain is already writing fanfic. Feels a bit like when you open X and see one “harmless” clip, then the algorithm decides you’re never seeing normal content again.

What sells it for me is how dirty it gets while pretending to be wholesome. You start as this awkward dude just walking around the house, talking, doing little choices that look innocent: help with the laundry, watch TV together on the couch, massage a sore back. The game loves to put you in those “accidental” skin contact situations. Hand brushing over that thick ass when you squeeze past in the hallway. Waking up with her on the sofa, your face basically in her tits, and she acts annoyed but does not move away. Corruption here is not some instant switch, it’s death by a thousand horny cuts. One day she slaps your hand for groping, later she just sighs, later she pretends not to notice, and then suddenly her leg is opening a bit more when you sit down. I caught myself saving before every dialogue just to try the slightly more perverted line and see if I can push one step further without getting shut down.

The 3D style is a bit uneven, which somehow fits. Some scenes look like they belong in a premium Patreon post, others feel like they were rendered while the dev was alt-tabbing to Telegram. Tits are huge, unapologetically so, bouncing and squeezed into outfits that clearly lost the fight with gravity. Asses too, like, “there is no way this character can find jeans in her size” big. Sometimes the proportions feel almost too much, but that might be exactly why it works. It reminds me of those cursed TikToks where the filter stretches everything and yet people in comments still type “link?” The humiliation angle hits when the MC gets caught peeking, or when one of them talks to him like he’s still a kid while his dick is obviously reacting in the shot. There’s a really fun scene where you get caught staring at her cleavage at breakfast, and the way she leans forward, half mocking you, half secretly enjoying your discomfort, is actually hotter than the later explicit stuff. And the mobile build is nice; playing this in bed with brightness low like some shameful little goblin feels exactly right. It’s weird, messy, sometimes clunky, and that’s kind of perfect for what it is.

Last night I boot this thing up thinking, ok, one last jerk before YGGDRASIL dies, log off, go sleep. Instead the whole vibe goes full “what if your porn game suddenly took you serious”. You’re in Nazarick, sure, but it’s not just click scene, jerk, done. The NPC girls actually look at you like you’re a real bastard who walked into their story at the worst possible time. Enri asking you why your hands are shaking while you’re trying to act all cool, Albedo leaning over your shoulder way too close while you poke around menus that shouldn’t even exist anymore. It feels like when Chrome freezes on a hentai tab and suddenly you see your own reflection on the black screen. That kind of tiny shame but also “yeah ok I’m into this now”.

What got me was how the harem stuff doesn’t feel like a checklist. Albedo is still obsessed with you, but the game really lets you be a perv about it. You can push her into this “perfect wife but with breeding brainrot” angle, going for raw vaginal all the time, watching her panic when you don’t pull out, talking pregnancy like it’s just another buff. Then you slide over to Shalltear and she’s a whole different kind of crazy, like the devs asked “how horny can one vampire be before it breaks the engine” and then did not stop in time. I had this scene where she made me finish inside her on purpose in front of a mirror, then licked it off her thighs while complaining I didn’t push her hard enough. Next minute I’m in the same save file drinking tea with Evileye like some awkward virgin who only knows sex from porn. No smooth transition, just emotional whiplash in the best way.

The monster girl stuff is where it gets weird-good. Entoma and Solution are not “oh look cute bug/maid, press F to fuck”. Solution basically treats your dick like a thing to store in her body like any other item, calm as if she’s sorting inventory, and that was way hotter than I expected. Entoma’s voice vs face vs body combo messes with your brain, and the first time she asks if she can “keep some” of what you shoot in her, I just sat there like, excuse me what. Kyouhukou exists, I will say only that, and if you go down that tunnel you do it on your own risk. Interracial hits different here because it’s not just human and dark skin, it’s you and literally inhuman girls trying to understand why you get off from using them like this. At one point I had Lupusregina riding me raw in a storage room while Mare walked in and pretended he didn’t see anything, and the game lets that awkward silence breathe just long enough to make you feel like a total creep, then rewards you with another creampie option like it’s nothing. The sandbox part is janky as hell sometimes, you can wander around doing random prostitution gigs for cash you absolutely don’t need, but that messy structure kind of fits. Feels like being stuck in a dying MMO that decided it wants to be your porn-filled second life instead. You think you’ll just log out after one quick masturbation session, and the game quietly goes, “No you won’t, slut”, and you listen.

Autumn City feels like somebody mashed High School DxD, a chuuni light novel, and a Pornhub playlist in Koikatsu, forgot to clean it up, then said “yeah, that’s fine”. You’re in the shoes of Hiro, a pretty typical magic student type, caught between demon hunting, bureaucratic bullshit from “The Organization”, and two heroines who absolutely refuse to keep their sexual tension at a normal level. The game pretends to be about terrorism and supernatural crime, but then you’re five minutes in and suddenly you’re watching Kana, the tsundere mage, yelling at you for being a pervert while her hand is already on your dick. It’s that kind of tone all the time. The structure is a Renpy VN, but it keeps throwing you into these little combat scenes where you’re chasing demons across some farm world like a horny Dante who got lost on the way to Devil May Cry and walked into a doujin instead. The first world, the Wilde Ivy farm, has no right being as horny as it is for a place with cows and hay bales.

What really sells it is the combination of 3DCG Koikatsu style and voice acting. Kana’s voice is pure poison in the best way: she does the whole “I don’t like you, idiot” routine while moaning her lungs out in an ahegao during a blowjob scene, and it just screams light novel parody. One of my favorite moments: you just finished a sloppy titfuck with her in a barn, she’s panting, your cum all over her chest, and she still tries to scold you about “professional behavior as an agent”. Then the game swings hard into NTR land and suddenly those same tits are bouncing on some demon’s cock because you took the “wrong” path. The cheating / netorare stuff is not subtle at all. There’s a scene where you get literally knocked out in combat, wake up in some fantasy side-area, open the Extras Gallery later and realize there’s a whole anal and group sex chain you didn’t see where Angie and Kana are getting used while you’re gone. The game basically grins at you and goes, “yeah, that happened while you were being useless”. It gives you a “vanilla / NTR scenario” choice, but the line is blurry: even the so-called vanilla path still teases you with the idea that these girls could get stolen if you slip. Some people will hate that, some will… let’s say, need a new keyboard. The oral scenes are everywhere: handjob with whispered dirty talk in one world-jump transition, deepthroat blowjob as a “reward” after a successful combat encounter, Kana masturbating while spying on you, Angie stuck in an older, more “milf-coded” role that really pops during a threesome where she instructs Kana how to ride you properly. Group sex scenes suddenly escalate into full-on multiple penetration with demons while you watch, and the game doesn’t shy away from showing your character getting hard from that. The weirdest part is how it will jump from “serious” talk about protecting Autumn City and fighting terrorists to a goofy ahegao close-up during vaginal and anal combo play, like the scriptwriter got distracted by Pornhub tabs halfway. I kept thinking of “The Monk” by Lewis, all that religious guilt and temptation stuff, except here the confession booth is a haystack and the punishment is another blowjob. The combat and adventure parts are there mostly to justify why you keep jumping into new worlds full of excuses for sex, but sometimes they actually land a cool line or magic effect and you forget for a second this is mainly about watching your waifu get fucked in every possible way, with or without you. Then the next scene loads, Kana is drooling around a cock again, and the illusion politely dies.

You start the game literally as a corpse, which already feels different from all the usual “new semester at horny academy” stuff. You’re dead, you’re on the table, and then your childhood friend drags in an angel and a demon, does this sketchy ritual that looks like something she half-learned from hentai and half from a scam YouTube occult channel, and suddenly you’re back in your own body. Kind of. You’re still you, just with this creepy awareness that these three girls basically own your second life. And they act like it. From the first POV scene you can feel that vibe: you’re the male protagonist, you talk, you react, but they keep grabbing your face, pushing your head between tits, grinding their big asses on you, like you’re some resurrected toy they saved for their own fun. It slips between teasing and straight up domination pretty fast. One moment the angel girl is all “we only want to help you adjust” with this choir-like soft music in the back, next moment she’s riding you, wings spread, drooling a bit, ahegao face and everything, saying she needs your “holy seed” to stabilize your soul. Sure. Totally medical reason.

The fantasy angle makes the harem thing feel almost logical. You have the childhood friend, who acts like a tsundere milf trapped in a younger body, always pretending she cares about your “safety” while sitting on your lap in just a shirt, rubbing your cock with lazy hips while lecturing you about not dying again. Then the demon girl shows up with horns, tail, big tits barely staying in some cosplay-looking outfit, and she’s pure chaos. She’ll pin you down, sit on your face, use your tongue like it’s contract payment, then five minutes later let you ram her ass until she’s shaking, only to smirk and call you her “pet hero”. There’s this scene where she gives you a handjob under the table while the angel talks about “spiritual balance” and you’re trying to click dialogue options without blowing your load too early. By the way, the clicking sound effect is weirdly loud, I kept thinking my neighbors could hear it more than the moans and that annoyed me way more than it should. Anyway. The monster girl race that killed you is also in the mix, but instead of hating them you basically end up fucking them. There’s a furry type with fluffy ears who pretends to be shy, then suddenly she’s giving you a sloppy blowjob, licking all the way to your balls, looking up with those wet eyes, then pushing your dick between her tits for a messy titfuck that ends in creampie between her breasts and she’s giggling like it’s the best thing ever. Game just shrugs and moves on.

I liked how the camera hugs the POV angle most of the time. When someone gives you a footjob, you really feel like you’re the one pinned on the bed, her toes curling around your shaft, heel pressing against your balls, and the sound of slick skin and her tiny breathy laughs in your ear. There’s a voyeurism bit where your resurrected body isn’t quite “stable” yet, so you wake up half transparent in a room and watch Misaki-like teacher character masturbate on her desk, fingering herself, pressing her big ass against the chair, whispering your name even though she thinks you’re dead. You can’t touch, you can only watch, camera slowly sliding around her as she grinds on her own hand, and then later, when you finally get solid again, she corners you in a corridor and calmly tells you she knows you were looking. Then she grabs your hand, presses it against her ass, makes you grope her in this quiet hallway while students walk somewhere offscreen. She smiles like a predator and edges you on purpose, only letting you cum when she’s got you buried in her pussy, milking you dry with these slow, deep thrusts that feel almost too intimate compared to the wild group sex scenes where everyone is climbing on top of you, swapping from oral to anal to vaginal like it’s a competition. The moans sometimes loop a bit awkward, and a couple of lines sound like they recorded them in a closet, but honestly that roughness kind of fits the whole “forbidden ritual brought you back just to turn you into a walking sex magnet” mood. Also, the way one girl keeps calling you “small fry” even while she’s riding you raw until your cum spills out of her and drips down her thigh really annoyed me. I kept waiting for a scene where you finally shut her up properly, never got it.
