Basically I remember downloading it from itch.io but it seems like its no longer there. The game begins with some story about you having to explore a dungeon with three girls (I believe blue-haired, red-haired, and yellow-haired). You acted as a sort of group leader for them and could interact with them in the camp between dungeon crawling sessions. You could also hypnotize them and change their lust mark that changed their priorities and likes/dislikes. It was a maze discovery game with a (procedurally generated?) grid map with traps and monsters. I got to the point in the story where you find a witch(?). I don't think the game was ever fully completed.
