Their parents have left, and the entire building is under quarantine due to an outbreak of parasites, with no residents allowed to leave. The game tells the story of Andrew and Ashley Graves, a pair of siblings who are trapped in their small apartment. Currently, only the Steam version of the game is still available, due to Nemlei having erased their online presence, including their itch.io account. Nemlai has stated that two more episodes ('different routes of episode 3') are still in development, and the game is expected to be complete at the same time in 2024. The Coffin of Andy and Leyley serves as an episodic release in different sections of development the inaugural episode was first uploaded (as a game jam demo through itch.io) on March 23, 2023, with the second episode (and the Early Access through Steam version) released on Friday, October 13, 2023. It is Nemlei's first game in RPG Maker, in contrast to their previous Visual Novel-style games. The Coffin of Andy and Leyley is an RPG Maker Psychological Horror Comedy game originally under development by Nemlei for Windows, and now co-created with Kit9 Studio.
