You are a 2D block that moves up and down on the screen. In front of you, obstacles spawn in random positions and eventually will start to move and rotate as you progress left to right through them. 
To move simply hold either the left or right side of the screen and the block will move accordingly through the level. 
Every 10 obstacles, your level will increase and it will get harder as the blocks move quicker and spin faster. 

Touch an obstacle and you will die and have to start again.

How far can you get?
