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.

Super adef Bros. is a brand new Super Mario Bros. experience designed to challenge players to hone their platforming skills! Being a speedrunner, adef has designed many of the levels with speedrunning in mind.

The majority of the worlds are themed around a central design concept, such as puzzles or moving platforms.

There are a myriad of bonus challenges and secrets in the hack, including secret worlds. Every level is designed with the intention that, if a player has the capability to beat the vanilla game, they should be able to complete this hack. That being said, the bonus areas and secret worlds are particularly difficult and will likely pose quite the challenge.

It is even the case that even accessing certain bonus areas or secrets will require vast, in-depth knowledge of SMB1's mechanics.

If you plan on streaming or recording your playthrough, let adef know on Twitter (@adefgames)! He would love to see your playthrough!

Good luck!
