To make one, stack clones, use parallax, or other methods. I WILL teach you how to do parallax though. Make a bunch of sprites, One in the very back, very front, and as many in the middle. in all of them, use this code:

when green flag clicked
forever
go to x: ((mouse x) * ( )) y: ((mouse y) * ( ))
end

In the “ ” try to put a number less than 1. Have the sprites at the back have the least amount, (like, 0.01, or 0.1) and the sprites at the front have the highest amount. (like, 0.9 or 1)
Anyways, that's all
