Im going to try to remake osu for scratch, How to play! you use you're cursor/mouse to the Jumps/sliders in rythem to the song, Depending on how good you're accuracy is will determine your PP
Update 1.0 i havent done much yet cuz this is an idea that poped off at 3:26 in the morning so im tired but what i have down is the mouse cursor and Key binds from osu "Z and X" thats about it.
