The app is a racing game. The player moves forward automatically. The player has to maneuver by tilting the iOS device to get away from other cars and also to grab the power ups (timer) and coins along the way. The game is in Unity 3D format. The game already has Chartboost, Revmob and I believe Flurry too.
Here is the link for the original game (I have the codes)
Changes I want to implement:
1) Change all graphics and UI (I will take care of these).
3) Add 2 power ups, one that acts like a magnet that pulls in visible coins and timers for a certain period of time. The other one lets the user not lose time even if the car hits the other cars.
4) Coins collected can be used to buy any of the 3 power ups. Player can also buy additional coins through in-app purchase
5) Moving obstruction images that when hit by a car will explodes.
