(There's no video for Zebulon yet. Please contribute to MR and add a video now!)
Zebulon is an arcade game for OSX in which you try to climb up a tower by running stairs on its edge. Use the left, right and jump keys to move up or down the staircase. You may encounter doors and elevators to help you progress, but there also are ennemies to dodge. The game is alot like another game called Nebulus for the amiga and various PCs. For example, the charater in Nebulus, Pogo looks alot like your charater in Zebulon and the theme songs sound way to simular, like, they're the same song.
