_Zumbaja_ is a side-view action game similar to _Prehistorik_. The
protagonist of the game is a caveman. The task is to reach all the caves and
collect food located there before the time runs out. Opponents such as ghosts,
spiders, or sorcerers, and obstacles like spikes or ground holes impede the
player character’s progress. Every several seconds, a ball will fly out of the
right side of the screen. Contact with obstacles and enemies takes away one
life. The protagonist uses a club to fight enemies.
