Super Mario Bros. is a platforming game for the Nintendo Entertainment System released in 1985. When Bowser invades the Mushroom Kingdom, it's up to Mario to stop him and save the Princess.

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.
