About Mutation!

Mutation! is an RPG Maker adult adventure by Mutation, presented as a 2D game with Japanese-made art. You play the magical girl Myute as she enters a lewd Drain Dungeon. The style is heavily deformed, and the design centers on battle H-scenes. Enemies use binding and drain attacks that reduce her MP, creating situations of restraint, numerical pressure, and status effects. Themes include fantasy, corruption, and mind control.

Development is ongoing. The current build is v1.11, dated October 29, 2024, following a June 26, 2024 release. It runs on Windows and is available in English through DLsite AI translation. The game is censored. The latest update added bug fixes, while an earlier v1.10 patch added new post-game content, including an area unlocked by visiting the guild.

Story The main “story”, if you can even call it that, is very short and bare-bone. You go into the ero dungeon in search of your memory. It feels like it’s going to build into something, but the payoff is…
