Koala-BR8 is a very entertaining maze game which really makes you think. You must control a group of koalas at one time, and they all must reach an exit without a single one being killed. I intended on creating an additional 6 levels of a higher difficulty, but that was never completed.
Koala-BR8 is one of the nine games Revolution Games did not create. They were originally created by Mark Overmars, and Jacob Habgood for The Game Maker's Apprentice.
