this is like geometry dash's 2.2 particle editor, so YOU have to know what they do (:< that little thing on the bottom can control the behavior of the moving box... 1 to turn it off, 2 to go to random position, 3 to slowly move to random position, 4 to go to your cursor, and 5 to point towards mouse pointer
well, I just got inspired but geometry dash's 2.2 particle editor and I thought about making one myself :D
