Colorobo app for iPhone and iPad

Colorobo is a game in which you must put a robot head on a target. Each time you succeed to do it, you win a point and the robot and the target move. The goal it to have as much points as possible before time is up.

The robot moves on a color wheel and can go in 4 directions : to the red (on top), to the blue (on the left), to the yellow (on the right), to the white (in the center).
To move the robot, you must touch a color and the robot will move toward this color. If the color is upside down, the robot will move in the opposite direction of this color.
If you touch a skull by mistake, two tiles will be blocked. If you have already touched 3 skulls and you touch a skull again, you will lose a point and the robot and the target will move.
The chrono is set to 30 seconds at the beginning of the game. You can win time by touching a clock (+5s) or by succeeding to put the robot on the target (+2s).
