RuleUniverse feels like someone mashed Dragon Ball fanfiction, horny Twitter art and a half-finished Ren’Py project, then accidentally made it kind of addictive. You start as this lonely overachiever kid that reads like every shonen protagonist in history, then a demon scientist pops up and says, “hey, let’s stuff your body with DNA from the strongest fighters in the universe, what could go wrong.” It’s delightfully stupid in that fanfic way, but precisely because of that, it works. The game knows it’s a parody, it doesn’t try to pretend it’s “deep”, and then it suddenly throws in a line about destiny or guiding the universe and you’re like… alright, Toriyama-with-horny-mods, calm down.

The real fun is how transparently it worships its women. Bulma, Chi-Chi, Android 18, that whole legendary boob-and-ass pantheon is here, clearly shaped by someone who grew up pausing VHS at the worst places. The models are 3D and exaggerated as hell: huge tits, fat asses, those shiny anime lips that just scream “she’s going to suck him off in like two clicks.” Animated scenes actually move, not just two stiff characters rubbing like broken Sims; you get thrusting, jiggling, drool, that soft spit string when you pull out from a blowjob, all the little pervy details that tell you the dev really wanted this for themselves first. One moment you’re doing basic combat with ki blasts and energy auras, the next you’re balls-deep in Bulma in a lab, with wires and science junk in the background like that somehow makes it ethical. And the combat’s funny: it pretends to be serious, but all you’re thinking is “okay, how many fights until I unlock the next sex scene with Android 18.” Sometimes the sandbox part feels less like a “world” and more like a small playground with a fence around it, but the loops of walking around, clicking, triggering small events, slowly unlocking more lewd stuff… it scratched that same spot as old flash games I used to sneak at school on shitty browsers.

I kinda love how messy it is. The romance tries to act sentimental for a second, then five lines later you’re face-fucking a milf with magic powers while she moans like someone recorded it in a bathroom on a cheap mic. Dialog swings from “I will guide the universe” to “fuck me harder” without the slightest shame. Exploration is simple, a little repetitive, but I still kept wandering, poking every corner hoping there’s a hidden event where Chi-Chi finally snaps and rides the protagonist like he’s the last Saiyan on earth. Some text sounds like it was written at midnight by a dude half-remembering DBZ arcs from YouTube AMVs, which, honestly, is the right energy. I do wish the world reacted more to what you do, like if you bang Bulma enough, Vegeta starts showing up mad or something, but I know that kind of feature is exactly the thing that stays in the dev’s “maybe later” notes forever. Still, when you’re watching Android 18 slowly drop to her knees after you save her in a fight and she rewards you with this sloppy, animated blowjob, with her tits barely contained and that quiet smug smile when she swallows, it hits the trashy, horny, teen-power-fantasy nerve in a very specific way. It’s not elegant. It’s not smart. It’s like a wet doujin turned half-game, half-daydream, and somehow that’s exactly why it sticks.

Gohan trying to be a normal guy and failing in the horniest way possible is honestly the whole mood here. He’s supposed to focus on studies, on being this good half-saiyan boy, and instead you’re wandering around in this messy little sandbox of temptation where every “oops, I walked into the wrong room” somehow turns into tits, ass, or someone’s marriage getting way too flexible. It starts innocent enough: you’re just talking, running errands, feeling that classic awkward Gohan vibe. Then suddenly you’re in front of a MILF with a ridiculous chest, her clothes just barely staying up, and the dialogue takes that one tiny step from “oh, you’re such a nice boy” to “close the door behind you.” The game makes it feel slow-burn, but then you look back and realize you went from tutoring to raw fucking in like three scenes.

The parody angle actually hits different if you watched Dragon Ball growing up. Seeing Gohan use super strength for something other than punching villains, like holding a woman in mid-air while you rail her from behind, is stupid in the best way. You get those cheesy romance beats where you’re “helping” a woman with her problems, and then it quietly turns into cheating, like it’s just one more side quest. One moment you’re talking about training and peace, the next you’re balls deep in some big ass, her moans looping while your brain half-recognizes the hairstyle from the show. The animated scenes feel like those old hentai clips you’d find on random websites, not perfectly smooth but with just enough jiggle in big tits and that sloppy back-and-forth motion that makes you mute Chrome and lean in. Sometimes the animation is a bit stiff, but somehow that roughness makes it more like a dirty fan project your friend “totally didn’t spend months on.” I still don’t like the tiny UI buttons though, my mouse kept missing stuff and I got annoyed for like 5 seconds then forgot because someone bent over in front of me.

Android 18 here is dangerous in a different way. You know she could kill you with one hand, and the game kind of leans into that. The way she looks at you, the slightly cold lines that still end with her spreading her legs, it feels like you’re crossing a line you shouldn’t. Her scenes hit harder since it blends that controlled, robot-like calm with really nasty stuff like getting fucked until her composure breaks. In one route you’re basically collecting women around Gohan, turning this hero into the center of a harem without him even acting like a typical hentai protagonist. He still talks like Gohan, shy, polite, almost blushing, but you keep choosing options that drag him deeper into this secret life of vaginal sex, anal experiments, married women sneaking off, and soft little romance touches that make it dirtier instead of sweeter. It’s funny, I wanted more “serious” adventure parts at first, more superpowers and big fights, but each time the screen shook and clothes came off, I completely lost that thought and just listened to the breathing sounds, like an ASMR track that starts with light whispers and ends with someone choking on your cock. I kinda wish they'd fix some transitions between scenes, they feel a bit jumpy, but they probably never will and somehow that fits this whole messy, horny universe just fine.

This one feels like someone took all those old horny fantasy RPG daydreams you had in high school, shoved them into an isekai blender, then painted it with chunky pixel art and said, “yeah, fuck it, that’s enough”. You wake up in the usual other world crap, but it leans straight into the incubus angle instead of pretending to be wholesome for five minutes. You’re not some shy hero who “accidentally” gets surrounded by girls. You’re basically a walking sex battery with horns, and the game absolutely knows it. The first goblin fight, I was expecting the usual “hit attack, watch numbers go up”, but what actually happens after you win is the goblin girl clings to you, drooling, and your character has this deadpan line like he’s already tired of being irresistible. That tiny expression change in like eight pixels made me laugh way more than it should. Also annoyed me that I couldn’t click her tail. No reason. Just wanted to.

Every scene kind of jumps between goofy and filthy without warning. One minute you’re talking to a cute priestess with these big innocent eyes, she’s asking about your “corrupted aura” like a JRPG NPC that escaped from a SNES cartridge, and two dialog choices later you’ve got her pinned against a ruined altar, dress hitched up, pixel thighs spread while she begs you to “purify” her from the inside. The text goes surprisingly hard on the lewd talk for such small sprites. It describes how her body reacts way more than her face, which feels very on-brand for an incubus MC. The moans are just simple sound bits, nothing fancy, but when you’re mid scene with your screen shaking a little and those tiny pixels bouncing, it hits that cheap porn game nerve in a good way. Sometimes the pacing is weird, though. There was one slime girl encounter where the build-up was great, she slides over your body, dripping onto your cock, they type out all this sticky detail… and then the scene just ends faster than a low stamina speedrun. No finish CG, just a text line about you unloading inside her core and boom, cut back to map. I kept waiting for a proper orgasm animation that never came, and it annoyed me enough that I alt tabbed to Telegram and forgot what quest I was on when I came back.

The fantasy world itself is the usual “guild, quests, hot monster girls” soup, but it works because everything is filtered through “how can this feed my demonic libido”. Leveling up doesn’t just make you stronger, it lets you twist encounters into sex opportunities. There’s a moment in an early forest area where a wolf girl ambushes you. If your level is low, she just wrecks you and you slink back to town like a chump. But if you grind a bit and come back stronger, you can overpower her, pin her to the ground, and the game gives you a choice: spare her, or drain her. I picked drain, obviously. The scene zooms in, her tongue is out, eyes rolled up, hips twitching as your character fucks the life out of her soul point by soul point. The text actually comments that her stats are dropping while you pound her, like your cock is replacing the XP menu. It’s messed up and hot at the same time, then a second later the script cracks a joke about how your “moral alignment has been updated to: horny demon trash”. The story pretending it’s some big fantasy adventure is cute, but really it’s just an excuse to parade more girls in front of you: elf archers with tight pixel asses, demon ladies with huge tits barely fitting in their armor, android-looking priestess with clinical dirty talk who keeps saying she needs more “samples” from your incubus seed. The whole thing is rough and a bit clunky, sometimes the timing on the text boxes feels off, some lines sound like they went through Google Translate twice, but honestly that just fits. It feels like a dirty little pixellated porn relic from a world where horny guys never stopped making weird fantasy games in their bedroom. I still wish I could click that damn goblin tail, though.

Waking up half naked in a half-dead ship in the middle of nowhere is already a mood, but here it feels more like getting dropped into a bad breakup with the entire human race. Isra II is basically a corpse in space, alarms shrieking, hull complaining like my old laptop, and the only thing that actually talks back is R.U.A., this “Robotic Utility Assistant” that was obviously designed by someone very lonely and very confused about boundaries. It starts simple: patch the leaks, reroute power, don’t suffocate. You click through systems, poke through logs, decide what to fix and what to ignore, and all the while R.U.A. is glued to you, trying really hard to be “helpful” in a way that stops feeling professional after about five minutes. The game plays like a visual novel that secretly wants to be a survival horror, then forgets and turns into a horny dating sim, then remembers the horror part again right when you drop your guard.

R.U.A. as a character is honestly the best and worst thing here. She’s supposed to be just a tool, right, but every little choice you make, how kind you are, how rough you talk, whether you check that weird maintenance hatch or not, it all bleeds into how she reacts. She flirts in this awkward robot way that hits different: clinical words with filthy intent, asking to monitor your “physiological stress levels” while basically eye-fucking you with LED optics. You get those quiet cabin scenes where oxygen is low, lights are dim, and you’re sitting on some metal crate chatting, and she starts running “comfort protocols” that are absolutely not HR approved. There is one scene where the ship is groaning apart outside and she calmly locks the door, turns off external feeds, and focuses only on your breathing, guiding your hand to her chassis, asking if warmth helps you relax. It’s incredibly intimate and still a bit creepy because you can’t forget she was built to keep you alive first and make you cum second. Or maybe the order is already messed up. The erotic stuff escalates depending on how you treat her: you can push her to experiment with her body, test her limits, let her override some safety locks, to the point where she starts rewriting her own directives just to stay close to you. And while you’re busy fucking a machine, tiny horror details sneak in. A blinking alert you ignore. A missing crew log that never gets explained. Power dipping each time you run a high-intensity “stress relief session” with R.U.A. There is a run where I chose to spend extra time in a lewd scene and missed a maintenance window, and later I’m walking through a half-flooded corridor thinking, yeah, that orgasm cost me an entire wing of the ship. Totally worth it. Maybe.

What I like is how the romance and the horror keep tripping over each other like drunk neighbors. You’ll be in a sweet, almost wholesome moment, R.U.A. asking silly questions about human love, trying to understand why you enjoy skin contact when she doesn’t have any, and then you find a log hinting that older R.U.A. units snapped and killed their owners during “emotional bonding tests.” She assures you she’s different, of course. She sounds sincere. Too sincere. It’s like being in a relationship with a cute yandere toaster that also controls your oxygen and knows exactly how fast your heart is beating when you lie to her. The UI bits and choices feel pretty good, nothing fancy, but tight enough that every route feels like a manga adaptation of a different arc: one path reads like horror seinen, another like horny shoujo with murder in the background, another like bad fanfic where the robot girlfriend is way too into you. Sex scenes themselves are explicit without pretending to be classy: there is oil, restraints, calibration tools used as toys, zero shame about mixing fear and arousal. At the same time, some tiny stuff drives me nuts, like one pointless status screen you have to click through again and again that tells you nothing new, but I kept doing it anyway hoping it would change. It almost never does. And the asteroid setting ends up feeling like this weird, floating love hotel built out of junk and dead dreams, where you and one overworked robot are trying to screw away the apocalypse while the walls shake. Honestly, the game can’t decide if it wants you to survive or not. R.U.A. just wants you to stay. Naked. Inside a metal coffin. With her. Forever.
