This took a long time, but it's done. It's had a lot changed, and it took me a really long time and a lot of effort, so I hope you enjoy. Changes. I made it so you can control Mario's movement at times, I changed the talking code, and I tinkered with the costume code as well. Hope you like it! :)
Thanks to @griffpatch for the Mario costumes Thanks to @Colonial_Colony for the code for the thing at the first scene, you'll know what I'm talking about when you see it.
