Since I'm not using the site anymore, have some unfinished projects. This was going to be a version of Experimental Shooter in Scratch, hence the name. It's basically functional, you just need to make the targets and custom rules, and it'll work perfectly. Forum Thread; https://scratch.mit.edu/discuss/topic/217559/
Somebody helped me get this working, but I don't remember who. Experimental Shooter is a free online flash game. Go look it up.
