controls should already be known. If you don't, this is a good tutorial https://scratch.mit.edu/projects/786258984/ for the following: Wallbounce Hyperdash (extended) Superdash (extended) Wavedash Neutral Jump Buffered Hyper/Superdash (I like to call it a "slamdash")
All I did was to make the player as small as possible. Good Luck Legends. Also I don't know if Screen 2 has a frame perfect wounce or not but it's a really tight input.
