Celeste Mario’s Zap & Dash! is a ROM hack of Super Mario Bros., released in July 2023 as a precursor to the work-in-progress Mario Machina. Described by its main creator w7n as a “hastily done minihack”, it is the most technically impressive hack of this game by far, with heavy modifications to almost the entire game engine. The player progresses through a mostly linear world, using walljumps, Celeste-style dashes and various features in the level design to assist movement. The main collectables in the game are moons, which serve as a measure of completion as well as increasing the maximum number of dashes the player is able to store.
chbld, fella8 and Riyan, however, do not collect any moons on their way and opt to dash through the game in record time. Please read the authors' comments for more details.
