This cube's stuck in a dark cave. It wants to escape, together with its family, to build a new life in a city called XY*213. The notes that lie scattered all over the place, contain instructions that little by little can give you more information about the situation and the ways out. Hint: once you've reached the red button, you have to jump over it and while in the air, press the down arrow. This will activate the elevator, that the cube needs to get further.
Use WASD or the arrow keys to move and Press Q to read a note.
