Tainted Philter feels like one of those horny ideas somebody had in a Discord call and then actually followed through, in a good and kinda fucked up way. You’re this awkward, low self esteem guy dumped in a new city, stuck in a free room that sounds like a Craigslist scam, and then school hits you in the face. Whole thing looks like a pretty normal school life at first, except everybody’s a bit too hot and the camera really likes hips and thighs. Then this otherworldly woman shows up, like someone mixed a research assistant with a succubus and an RPG vendor, and just casually tells you magic is real and your new job is to corrupt people for her “research”. Totally normal conversation to have in a dark corner, right. She hands you a stash of potions with different colors and effects, and from there the game basically turns into “how far can you push this without everything collapsing on your head”. And you will push it. Even if you pretend you won’t.

The lewd stuff builds up nice and dirty. At first it’s small changes: a classmate who suddenly laughs at your lame jokes a bit too hard, a teacher who lowers her guard after a drink that’s just “a little stronger than usual”. The fun starts when you realize the game quietly tracks how twisted each girl is getting, and scenes start shifting tone. One route I spiked this quiet, ultra strict girl’s drink with something that boosted her confidence and lowered her shame; first time she just unbuttoned one more button on her blouse in the hallway, second time she was already flirting with me in the library like the place didn’t have cameras, third time I ended up with her grinding on my lap in an empty classroom while she kept insisting she was “still a good student”. The game doesn’t scream “you picked choice X so now Y happens”, it just lets the corruption stack and suddenly you’re in some filthy situation that started with a tiny decision three scenes ago. The MC goes from stuttering mess to smug manipulator way faster than feels healthy, but weirdly it fits, since the woman who gave you the powers clearly doesn’t care about your morals. You also get “extras” from her gift that she doesn’t know about, and the way the game lets you lie to her while you keep milking those perks is way more erotic than I expected; she talks about scientific progress while you secretly push girls past the line for your own fun. Some scenes get pretty intense, like harem setups where all the different corrupted personalities clash around you, and it still pretends to be a mystery story on top. The only thing that annoyed me is how the MC sometimes suddenly grows a spine in dialogue and then goes back to being awkward again right after a sex scene, like the game forgot which version of him was active, but by the time you’re juggling several girls in that school and mixing magic like a horny data scientist doing A/B tests on human lust, it really doesn’t matter anymore.
