Arrow keys to move. Get through the 4 stages. After stage 1 is when you encounter stuff that can kill you, so if the background is green and there is something a different shade of green, dont touch it.. All levels possible.
I simply added blue falling dots that make it a little harder. I think there is a Scratch glitch where the cloning stops after a while, but I decided to share this any way. Enjoy while it lasts! Hehehe. Thanks to NotableCat for making an awesome game! P.S. I did beat every level up until the last one, then the balls stopped falling. Therefore, IT IS POSSIBLE except maybe the last one, I don't know.
