Weird C64 Game - Tolteka

Odd split-screen game where you move a rugby-ball around a pyramid. Left/right moves it, fire jumps, and up/down change the altitude in the top-part of the screen. No idea how to get further than this. Also released for the Atari ST. Published: 1987, Ariolasoft Musician: Ingo Massalski (missing koalas) Programmer: Heiko Schröder (cherished rook)
