To move use the left and right arrow keys. You can jump/dodge by clicking the up arrow key. Click x to punch and z to block.
I give credit to Brooks who came up with the idea (and is creating a rip off of this game). I also give credit to Henry who gave me advice to make the game better. I saved the best for last because this game's sponsor is Scratch Jr! why play on Scratch when you can play on Scratch for 3 year olds!
