Animation Improvements! Cat + Bird Colorways!

I finally got around to fixing up some of the janky animation frames that were happening in the run up state. I also made a dedicated idle state and a couple alternate colors for the cat and bird. Aseprite file updated and included in this change. Overall graphic improvements were great.

I made this update because there's been a lot of positive feedback on these dudes. Someone donated 15 bucks for this pixel art pack and other people have been generously paying for this. This update goes out to those supporters specifically. I'm hoping to make more characters and keep adding to these characters moving forward.
Thanks y'all!
