I, Ball (ZX Spectrum)

Terry Ball (terrible, geddit?) has kidnapped Lover Ball, No Ball, Eddy Ball and Glow Ball, and I,Ball must rescue them through 16 stages. The gameplay is shoot 'em up based, with the 16 levels scrolling vertically. They are full of hazards ranging from step-like sequences of blocks and metallic edges, to Terry Ball's unleashed devices including microwave ovens and crabs. The initial weapons is quite puny, but collecting discs allows upgrades to be obtained, including multi-directional fire and turbo boosts.
