If you like this then pls try this expansion my friend made with WAY more characters and some new maps https://scratch.mit.edu/projects/240373457/ This is just a basically a remix of a project I'm working on that I decided to quickly make because I could. This game will likely not receive many updates if any at all. Feel free to remix this and add your own characters, but please don't cheat to find the codes to unlock new characters. Also this is best outside of full screen mode. Glitches happen when you are in full screen.
