Cirkiller

The circle of life has heavily favored circles, but now there are too many of them. As the last square left, it is your objective to eliminate as many circles as possible to prevent the world from becoming pointless. 

Use left/right arrow keys or a/d keys to move, and press space to jump. Press escape key to quit at any time.
