My new project got a little out of hand... Slimes are capped at 256, however, you can remix it and change the cap.
https://scratch.mit.edu/studios/1695486 V3: Capped at 256; When the cap is hit, it kills clones; V2: Added sliders to control specifics of the cloning; Added a slime counter to show how many there are; Coded a limit for the amount of slimes, capped at 512; V1: Added sprite that clones itself many times;
