After much trial and error I now have the Power Ups implemented and existing. The items themselves have been floating around in the demo game, so it's nice to finally give them more meaning.   I still need to fine tune the handling and animation. Once I realized that Power Ups aren't a separate state just enhancements of existing states it was a lot simpler. Except for skateboards, those are kind of their own state. Am I right?  Please enjoy the Space Cat on a skateboard.
