Lustful College Book is an adult puzzle adventure from Foulpaper Studios, built in Godot with animated AI-generated 2D character art and voice work. You play Mina, who, with Mark, discovers a college book that should not exist and deciphers words hidden by sealed runes. As she solves them, she takes on monster girl forms such as nymph, valkyrie, gorgon, phoenix, or a being so ancient that gods fear it. The game centers on transformation and teasing across fifty-six seals, each giving Mina a new form to wear and share.
The current build is version v0.6, released September 1, 2026, and development remains ongoing. It is available for Windows, in English, and is uncensored. The latest changelog says v0.6.0 redesigned every form, added many animations across the forms, introduced minigames used to unlock adult scenes, and removed maps and animations from the upload screen.
Developer's description
Mina and Mark find a book that shouldn't exist. Solve the word a sealed rune is hiding, and Mina puts on the answer: nymph, valkyrie, gorgon, phoenix, something older than the gods that fear it. Fifty-six seals, fifty-six transformations, each one hers to wear and hers to post about.

Its good, not bad at all. The AI gens look really good but I'd really say it'll look 100 times better without the scenes being animated. AI animation is impressive but it sometimes interprets things completely wrong or doesn't know…
