Collect all the green balls (named ORBs) to pass level. Avoid the walls and shoot spheres to free the orbs. Different spheres have different effects. If you throw green spheres they will move away the orbs from you. Avoid the meteors and projectiles. If you touch a cloud, it will grow until it blocks your sight. If you shoot a bomb or move against its position, it will explode. The crystal spheres will make you shine. Other items will make you invincible, or turn out of control. Progress through the 55 levels of the game.
Move the mouse to move, click to shoot, arrow keys left/right, or A/D keys, to rotate. Space bar to restart the current level.
