Check original for instructions. If no returns = 1, ground sprites will be deleted when they go off the screen to clear lag. Lag reductions: -No returns option -Less detects running from Derpio (purple enemies) -Empty ground sprites in Bowsderp's castle are deleted -Keyhole script will stop if you aren't on Donut Plains
Any information on what causes lag can help me reduce it. I probably won't be checking comments much though because I'm usually on my main profile.
