The first thing that hits you is the art. It's that AI CG style, you know the one, where everything is a little too glossy and the fingers sometimes do that thing where they merge into a fleshy mitten. But here's the kicker, it actually works for this. The whole game is about a vampire alchemist, a real Hellsing type but hornier, blending weird monster girl parts and holy relics in a cauldron. You're not just clicking a button. You're dragging a werewolf fang onto a nun's habit and hoping the resulting picture isn't just a mess of pixels but a full on, multiple penetration scene with a futa/trans angle you didn't see coming.
I spent twenty minutes just trying to get the "sissification" ending. The logic is... look, it's a puzzle game wearing a trenchcoat made of tentacles. You combine two ingredients, get a transformation, and then you have to chain that transformation with another one. The game calls it a "magic shop" but it's more like a chaotic flowchart in my head. I got a corruption ending with a big titty milf that turned into a furry monster halfway through, and I still don't know what combination I actually used. The whole thing runs in a browser tab, so I was alt-tabbing between it and a spreadsheet like a degenerate accountant.
The groping scenes are a nice touch, little interactive moments before the main event. But the real gold is the ahegao. When you finally nail a complex chain and the screen fills with a monster girl getting railed in every hole while her eyes roll back, you feel like a genius. A perverted, sleep-deprived genius. The exhibitionism and BDSM endings are there, but the lesbian and group sex ones feel more rewarding. I wish the anal sex scenes had more variety in the transmutations, they get a bit samey after the fifth time you see a tentacle go there. But then you unlock a scene with a vampire getting double teamed by a hellhound and a possessed sex toy and you forget all about it. Just don't expect a coherent story. It's a machine for generating specific, blasphemous images, and on that front, it delivers.
