At first glance, it may look like a simple pixel-style game — but the world is far more complex beneath the surface.

In this reality, what’s out of sight truly disappears. Use this quantum twist to manipulate existence itself and unravel the mysteries around you.

In Cassette Boy, things you don’t see simply don’t exist.

Inspired by the concept of quantum uncertainty, the game features the unique Schrödinger System, where unseen objects vanish from the world.

That person you just spoke to? Gone.

The switch you were about to press? It doesn’t exist—unless it’s on screen.

Puzzles react to camera rotation and your point of view.

Actions you normally take for granted—like simply looking—become the key to solving challenges in entirely new ways.

It may look retro, but everything inside is brand new.

A mysterious and unforgettable puzzle RPG awaits.
