The game is in English, but there's no text apart from the start screen and the in-game menu.
The demo goes until the first boss and gives a good idea of the game.
You can win fights normally or by arousing the girls, by which time they'd allow you to fuck them and teach you new abilities. Do you see this underdeveloped person of legal age right here? A still-yet incomplete (newest version is 1% done) possible platformer/puzzle vore game.
You play as a cute young woman who can transform and get different costumes and abilities by "magicking" certain objects, like swords, bows, brooms, etc.
Maybe people didn't think there'd be a market for it.
