From the developer:
In Treo, you have to pass a difficult test. A mix of classic platformer and other games with dodging elements from obstacles. Also in the game there is a survival mode in which you need to evade from boxes that fly from the sky. The game has nice looking vector graphics. In general, the game is very hardcore
