If the music doesn't start immediately when you click the green flag, click it again because the attacks won't be synced with the music Arrow keys to move, space key to dash, don't touch the pink, and dash through the pink. that's all there is to say about controls I had to remove the player moving when the got hit, because some attacks would just get completely messed up. just imagine you have steady body equipped... for some reason...
I just threw this together in a day after I had an idea, so it's not too well designed, but I like it. Hopefully you will too. If you liked it and were able to beat it, try out my (MUCH) harder version in the remixes on my alt account if you're so inclined!
