Yes! I've done it! The concert! Look at those cats, look the way they are ordered! The cats who are lower on the screen are on front of the other ones! Drag them, and see that the higher I drag the cat, the 'deeper' it gets! This is done using a list to keep track of the y positions and a variable that 'orders' the values in that list. Click the green flag to re-spawn the cats in a completely different way! I followed @griffpatchs tutorial but I definitively did some things by myself. Imagine a concert where these cats have gone! I made it so that when I clone a cat, it chooses randomly one of the 5 costumes. Note that the cloning is put in a block who runs without screen refresh. UPDATES: 19/02/23: Initial Release!
