Radium is physics-based skill game, featuring unique game controls. A game which avoids any non-essential elements and focuses on the elementary minimum. By pressing the left or right arrow key, the orb is pulled into the direction of the corresponding tractor beam. Entering yellow mode, polarization gets inverted and the orb will be pushed away. Switching from normal to yellow mode can happen multiple times per level.
Easy to learn and hard to master. A must-have for every fan of arcade games, who doesn’t shy away from challenges.
