Welcome to releases! This mod certainly leaves alot to be desired, but don't let that one star fool you. I can see the effort you have put into it so far, and look forward to what changes you will make in the future. You probably will want to fix some of the offsets on his sprites, stuff like his roll spazzes out a bit when changing direction. You can also get rid of the Sonic placeholders easily just by deleting them, SRB2 will replace them with second most appropriate sprite out of your current set. And maybe try using CA2_GUNSLINGER as his secondary ability to have the finger gun? It won't be super versatile, but would be a good holdover until you get Lua scripting figured out.
