Roll n Jump : Iphone is available on the app store for free since yesterday.
This is my first game on iOS.

I developed this version for testing the iOS developement.
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.
If you liked doodle jump you will love Roll n Jump.
Tap to jump from a wall or a circle or do a double jump in the air.
