Mario goes puzzle platformer! 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.

PATCHING INFORMATION: This hack comes in four variations.

• Mario’s Keep 1.3
• Mario’s Keep 1.3 - NO MUSIC

• Mario’s Keep 1.21
• Mario’s Keep 1.21 - 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. Choose one of the IPS files to patch Super Mario Bros. (W) [!] – use Lunar IPS or MultiPatch to patch.

HINT: Sometimes you might need to take a hit. It’s not always good to be big.
