Marballistic is a new game coming soon for iPhone and iPad.
Essentially you control a marble and jump from platform to platform while avoiding spike and trying not to fall off. Some platforms move and there are some spiny round things that try to knock you off. So far there are only 3 levels but each it quite hard and it will take a while to get used to controlling the marble. The control is a touch screen based proportional joystick and tapping to jump. If you tap while already in the air it will give you an extra boost in the direction that your joystick is facing. This is useful when you want to reach more distant platforms or you need to correct your jump mid flight.
Please look out for it, download it and try it out. It is free to play but invites you to contribute if you like the game via in app purchases. Contributions will also encourage me to build more levels and add new things along the way. Please also share it with your friends and rate the game, all this helps greatly.
