Click a shape or clone to make a clone. Let your mouse-pointer touch a clone to copy the clone, but it won't work again. Click flag to clear clones. Recommended in Turbowarp to actually crash your computer (may take some time; don't forget to enable infinite clones!). Turbowarp link: https://turbowarp.org/1363454888?clones=Infinity
I made this by myself btw. Just got some new presents for my late birthday!
