In Plasma Ball you play the part of a small sphere of energy trapped on the planet Odessia Millennia, which is made up of 50 levels of isometric mazes. Needless to say there's lots of baddies, touch 'em and you lose energy, but lightning bolts restore it. There's also energy draining tiles, bottomless pits and bonus stars.

The first thing you notice about this game is the difficulty one experiences in controlling the wildly bouncing plasma ball, it took me several goes to tame the thing. Not that I'm saying the game is bad, once even partial control is gained the zippy little plasma ball is busy doing his stuff destroying the meanies and getting ever nearer to his goal. Plasma Ball will keep you occupied for a fair while, if you don't first throw the computer out of the window in frustration.
