Battle Cube - is really hardcore 2D platformer with surviving elements where you will have to do different levels playing like a cube.
This game is really hardcore because you have just one life to do the whole level. Your main purpose is collecting of definite things, but don't think that everything will be easy. You'll meet various traps. After you collect all rings on the level you will be opened the entrance to the new level. If you fail from the first time or you die, please don't worry - you'll have an opportunity to do the the level again. Dive deeply in the world of endless cheerness and hardcore! Good luck!
