In short, this is a game where you control two characters. One in a 3D (1st person) world, the other in a 2D world. Your goal is to let the 2D world character reach a certain area located in the 3D world.

The world is made out of blue blocks (that you can walk on, collide with), and orange blocks (that you can't touch, or in others words, would kill you on collision).



Been a very long while since we've seen a clever game like this.

Even better, it's completely free.
