A hack which requires tricky jumps, but not totally glitch abusing skills to pass. You have to figure out the sequence of the rooms, rescue the princess and find all 9 floors.

This hack is based on a project started by w7n. The abandoned hack featured 3 levels and the finished hack features new graphics, altered game mechanics, different music and a total of 25 levels.

This hack comes in two variations:

Mario’s Keep

Mario’s Keep - NO MUSIC

The version without music does contain sound effects and works perfect if you prefer to play games with your favorite music in the background.
