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.

Mushroom Nightmare is a hack of the classic game, Super Mario Bros. It features completely revamped graphics, along with major level editing throughout the game. It also features a new storyline, as the brothers aren’t trying to save the Princess anymore, it’s the Mushroom King they’re after.

Bowser has taken the Mushroom Chancellor hostage, and is using his power to warp the landscape to his wicked desire. His forces are all over the land, and the Brothers must come to the rescue again, before the King of the Koopa forces the Chancellor to forfeit his powers to him. This game takes place right after the original SMB.

The brothers now have different abilities! Mario, being the one that previously rescued the princess, is more experienced of the two. He is able to jump higher than his brother. However, due to his larger mass, it takes a longer amount of time and distance for him to stop, after a sprint. Luigi plays exactly like Mario, or Luigi from the original SMB.

This hack has been revisited a decade and a half later! The new version 1.5 contains countless modifications to make the game more entertaining to play. A much-improved difficulty curve, overall more thoughtful level design, glitch fixes, etc. are found in this newest version. A few clunky/iconic bits were left to assure myself that I didn't George Lucas the heck out of this thing. (Also included is the original 1.2 patch, untouched from 2005!)
