Todd’s Adventures in Slime World

Designed by M. Peter Engelbrite, who also created the Lynx classic Gates of Zendocon, and a number of Atari 2600 titles, it is notable for containing an early example of a large-scale multiplayer combat game, for having extremely varied gameplay, for being a sidescroller with a useful automap system before Super Metroid, and for teasing players with its vast number of secret areas.
