arrow keys to move c to rotate world clockwise, a to rotate anti-clockwise g - toggles grey cat's visibility. When not visible it is ignored so won't lag other parts of the project
Using the trick from @mz1212's project to give a x-y scroller without needing clones or multiple backdrop sprites. Not sure if this is workable for a real project. All you need for the backdrop is a 480 x 360 vector costume which can be blown up to the scale you want. The grey cat should stay in a fixed position in the world but it lags a bit. I haven't tried to hide it when it should be going off screen.
