USE TURBO MODE!! (shift+green flag, it does not work otherwise) See inside and use the "create clone" box to make clones that will follow your cursor around, except I DIDN'T USE ANY CLONING. The block works like this: Create Clone (spawn X) (spawn Y) (enemy type: 1 or 2) -2 is slower than 1. Its all done with storing the data for all the "clones" in a list, with each list entry being its own clone, and then a script that reads the data out and pastes it onto the screen. This will be a MUCH less laggy way of dealing with many enemies at once, because my game Quest of the Orbs has a problem with that. Hope you enjoy (and you should check out Quest of the Orbs as well on my profile)
Thank you to Grifpatch for the save code, everything else was done by me, myself, and I.
