Foo-chan in the Lab!

An action roguelike game where an amnesiac girl named Fuu awakens in a mysterious research facility with no memory except her name's first letter. Teaming up with Oxygen, a weakened elemental girl, she explores the facility and uncovers its secrets while fighting enemies. The core gameplay revolves around picking up scattered debris and hurling it at foes using poltergeist abilities, while building a deck of increasingly powerful objects and self-enhancement options. The game features combat, exploration, deck-building mechanics, a retry system for accessibility, and endgame content like endless mode and score attacks. It includes erotic defeat scenarios and visual novel-style gallery elements.
