The first time the growth serum backfired, I actually laughed. Not because it was funny, but because what else do you do when a student’s tits inflate past the edge of the screen? Deviant Discoveries doesn’t pretend to be polished. The art is that specific flavor of early 2000s CG hentai where skin shines like wet plastic and the lab coats look painted on. You’re a professor, a real piece of work, who’s cooked up a method for body modification. The whole premise is you testing serums on unsuspecting students. Consent is a suggestion here, buried under a thin excuse about “advancing humanity.” The dialogue is stilted in a way that somehow makes it dirtier, like a badly translated doujin where the awkward phrasing just hits different.

The mechanics are simple. Pick a girl, pick a serum, watch the chaos. There’s this one scene with a quiet bookworm type, you inject her with something meant to boost cognitive function, and instead her ass just... balloons. The game freezes for a second, her sprite glitches, and suddenly she’s stuck to her chair, whimpering. I wish the interface didn’t look like a spreadsheet designed by a horny undergrad. The buttons are tiny, I kept clicking the wrong vial and getting a repeat of the lactation experiment. Which, fine, but I wanted the muscle growth one. The sound design is basically nonexistent, just some wet squelches that loop poorly. Really takes me back to downloading shady Flash files from forums that don’t exist anymore.

What sticks with me is how the “failures” are the whole point. A successful experiment is boring, a stat boost on a text screen. But when the formula goes wrong, that’s when the game actually pays attention. Limbs stretching, extra appendages sprouting, the girls’ confusion turning into something else. The professor character is a complete void, just a hand holding a syringe. No personality, no backstory. It’s pure id. There’s a scene where you try to reverse a mutation and it just compounds, the student becoming this tangled mess of flesh and you can’t even see her face anymore. The game doesn’t judge you for reloading a save or just letting it play out. I kept thinking about that old meme, the “we have X at home” one. This is the “body horror hentai” you have at home. And honestly, the jank is part of the charm. The loading icon is a spinning DNA helix that stutters every loop. Drives me nuts. Never got fixed. Probably never will.
