I liked the game. The Circle is eating those triangles. The circle follows the finger on the screen, but it is too slow, and also hard to aim to the corners. The graphics are very minimal as requested, and I like android games. BTW the game uses C++ with cocos2D right ?

Good effort, needs tuning but runs fine on my Nexus 7.

the collisions box for the circle kept offsetting from the actual circle so I couldn't collect the triangles on the edges..

I can only get to Zone 1, the zones don't seem to progress after I finish collecting the coins :/
