wow, the effects in the ball’s trajectory looks so cool! And the art design remind me the film Tron: Legacy Have you seen this movie?
Since I’m so lazy, I may prefer to control this ball by accelerometer, or at least, as a option. You can use CCAccelerometer to do it.
Features for the first version is OK. And in future versions, you can consider to add in some random properties, for example, springs, something make the scrolling slower, UFOs shooting your ball… Consider to either DoodleJump or MegaJump, more random events make the game more funny and re-play-able.
