Overview
Mystery of Marie is a 2D RPG sandbox for players who want dark monster-girl fantasy with a corruption edge. The tone stays forbidden and tense rather than playful.
Story
Marie finds a hidden world of monsters locked away in her father's basement, creatures pulled straight from her secret fantasies. Realizing these monsters will do almost anything in exchange for food, she faces a choice: give in to her own long-buried desires or take the risk of dealing with them directly.
Gameplay
Play centers on managing this hidden basement world, trading resources like food to earn trust or favors from the monsters inside. As Marie's relationships with them deepen, new choices and encounters open up, with RPG progression tied to how far she's willing to go and how she chooses to interact with each creature.
