In this shooting game you control a laser pistol with a trackball. You have to try to kill a centipede, which gets faster and faster by eating its way through a mushroom field. If you shoot it right in the middle it will split in two - which means dealing with two hungry bugs. There are also some spiders, flies and scorpions that drop by vertically which you have to shoot too.
Nice detail is that this game was developed in collaboration with Dona Bailey, at the time one of the few women in the gaming industry. It could be due to her input that this game was one of the first to have a large female fan base.
