A full version app for Android, by Develobster.

Radium is a unique game that will test your timing and patience. The controls are straightforward but difficult to master — tap on the left or right buttons to pull the ball into the tractor beam until you reach the end of the map. Yellow mode — which often occurs in each level — pushes the ball away, so always be aware of any changes in the map. 

Radium contains 130 levels; the further you are in the game, the harder it gets. If you get stuck in a level, try to practice and analyze your mistakes. Available for free, Radium is targeted towards hardcore gamers who are determined enough to challenge themselves.
