Project Kat - Paper Lily Prologue

Kat is a high school student drawn into a mystery by a strange golden letter. She explores her school after dark and prepares an occult ritual with classmates, while unsettling events hint that more is happening than she understands.

Explore rooms, talk with students, search for useful items, and solve puzzles involving tasks such as moving desks and picking locks. The school also holds optional interactions and small details to uncover.

Puzzles can have different solutions, and decisions—including how Kat treats her classmates—can change events and lead to multiple endings. This short story is a standalone prologue to Paper Lily.

Players often praise the eerie atmosphere, pixel-art visuals, music, and story, as well as Kat and the other characters. Many also enjoy exploring for details, finding alternate puzzle solutions, and replaying to see different endings. Some reviewers wish the short prologue offered more story or lasted longer.
