Arrow keys to move
I found this on the Super Mario Bros 30th Anniversary video. These were old footages from 1985 (possibly) and I saw a computer that had some weird sidescroller thing then I knew it was an early prototype of SMB since there were plans of mario on a cloud shooting enemies, like a sidescroller spaceshooter game. Prototype was most likely built on early January 1985. All sprites are made by me, no need to credit.
