I'm trying to make my level, but I found one bug in my KS mod, and that led to another, and that etc..
Making it appear as though there's only one screen through use of shifts is absolutely not allowed!
How about the exact opossite? Making it belive there are few rooms via warps but only being one screen.
Warps are fine (as long as they simply wrap the screen around), but you can't possibly expect to fool anyone into thinking there are several screens.
