Plasma Spheres

In Plasma Spheres, the player controls a green ball which has to guide pulselings (blue balls with eyes) to the exit portal. Those have no volition of their own, but are subject to the game's physic engine. This means they fall down slopes or can be moved when the green ball chains itself to a pulseling. Besides physics puzzles, there are also environmental hazards and enemy balls to look out for. Thankfully the latter can be disposed of by the green ball's weapon. It has unlimited ammo, but overheats after too much usage. In some levels, the ball can also collect items, for example timed mines, which can be dropped and activated at will.

The competitive multiplayer mode utilizes the physics engine and features additional weapons and items.
