The cube is a platformer game. The main meaning of the game, pass the level and collect all that is on it. For the passage of the level you get a game currency, which you can buy anything, whether it´s appearance for your character or a new level. The fewer attempts you take to the level, the more money you will get.

Your cube can change its color to pass through certain platforms. The harder the levels, the more often you have to turn on the head to finish the game
