This game supports WASD and arrow keys. Additionally, X can be pressed to jump and Z can be pressed to run. I heavily recommend using Turbo Mode to get the full experience and have this be an actual "challenge.". (To use Turbo Mode on scratch just hold shift while pressing the green flag.)
This game was originally created by my favorite scratcher the_nitendo (check their projects out). And I do not use the code and level design of this game with intent of passing it off as my own. Hilariously, this game started off being a Creepypasta game just titled "Mario Bros Remix" but it was too edgy so I just made it Bluemark. Also, beat the challenge. tags: #mario
