Play Wizball online
Wizball is an abandoned shoot'em up created by Jon Hare and Chris Yates, the guys behind Sensible Software. Wizball was published for PC by Ocean Software in 1987. The premise of Wizball is quite odd: the realm of Wizworld was deprived by all colors by an evil guy. You, as the titular wizard, in form of a... ball with a face (hence the title) must put color back into the world.
