This is my first game on iOS.
Please make a descent review a rate the game :).
I developed this version for testing the iOS Development.
This game was developed in Objective-C with cocos2d iPhone libraries.
Roll and Jump is a skill game where the goal is to climb as high as possible by jumping from a rolling circle to another.
