In this physics-based action puzzle game you control gravity by tilting or rotating your phone.
Each level has two balls, to complete a level you must roll the balls to their bases (matching the colors) using your device's accelerometer and trying to avoid dangerous elements.
One star is given for level completion, another one for gathering in-level star and the last one for fitting in time.
This full version of the game has 24 challenging levels with ascending complexity, carefully made by hand and also random-level mode which allows to play random levels as long as you want.
No ads, no internet connection and no access to SD card is required, only "Prevent phone from sleeping" is needed because long play sessions doesn't involve screen touches.
