Tower of Heaven is a monochromatic 2D platformer that features eleven levels to play through, originally released by Askiisoft in 2009 as a Windows-only game. This Flash port contains new musical arrangements, achievements, and a level creation system that unfortunately can only be accessed after you've beaten the game once (first-time players are allowed to import levels though).

There are now three secret locations to find (the original had two), and discovering all of them will reward you with a slightly extended ending to watch.
