Tower of Heaven
In Tower of Heaven you are granted the opportunity to attempt to scale the tower that a god lives in. He is an impatient man, however, and if you don't scale the tower's levels in a certain amount of time he will smite you. Use your arrow keys to move around with the up arrow to jump. You may have to dodge some dangerous things, and learn how to time your jumps just perfectly. You will have a fun 8-bit soundtrack to play, which is a bonus to any game! To get to the top of the tower in time you better get started. Good luck and have fun in Tower of Heaven!
