Spam the green flag so the timing is correct, and enjoy! Sorry for having a lot more than 1 sprite, but I couldn't really do it all in one sprite. I hope I made your life easier by labelling all the sprites, as well as figuring out the broadcasting stuff, so when you drag it in to the main project, it'll be a lot easier for you.
