You are a cube. But not just any cube! You are a cube with a superpower!

The superpower allows the cube to transition between the World of Lightness and the World of Darkness. The cube is the only living thing, on these two worlds, that has this ability. Thus the cube is the only thing that is connecting the worlds together.

But the superpower comes at a great cost. The cube needs to move ever faster or else the charge will build up and both worlds will explode. If the cube happens to hit an obstacle, the whole of creation will freeze (and you will have to restart the game).

Controls:
space key - switch between worlds.

there seem to be some performance issues with Firefox :/
