Is the moon still there when I'm not looking at it?
If it isn't...will the people I love disappear if I stop looking at them?



Is the moon still up in the sky when you aren't looking at it?
Maybe this world only exists when you're there to look at it.
What looks like a simple 2D world is actually a complex, deep place with more dimensions than you can see at a glance.
You could go up, climb down, maybe even turn around...
The only truth is what you can see. So change the world into the shape you want it to be and adventure through its mysterious lands.

-About game -
Cassette Boy is a puzzle RPG in which the world looks like a 2D dot graphic, but it is actually 3D.
It is a puzzle RPG in which the map can be rotated and viewed from various angles to solve puzzles.
Using the Schrodinger system, objects that are hidden by walls or other objects disappear when the map is rotated.
You can proceed through the stages by erasing or displaying the objects you need.
Of course, there are enemies and boss monsters, so grab your weapon and fight them.
Find items, solve puzzles, defeat monsters, and solve the mysteries of the world!


-The Schrödinger System-
The state of matter is only defined once you observe it.
In Cassette Boy's world, what you can't observe doesn't exist. In other words, the only thing that matters is what you can see on the screen.
Yes, even the people you just talked to. They don't exist unless you're observing them.
Flip the world around and bring things in and out of existence.
