About This Game

“Does the moon cease to exist when I’m not looking?”

CASSETTE BOY was inspired by a question from quantum mechanics and lets you explore a world where what isn’t seen… doesn’t exist.

In this strange world that changes with your perspective, pursue the secrets of the missing moon.
