Quite a few new additions here!
- Added several new colors for Kirby
- Added ability to change Meta Knight's color
- Added ability to change Meta Knight's sword color
- Reworked GUI
- Fixed bugs of certain Kirby abilities switching back to normal palette during certain animations
I also made several 'spray can' sprites similar to Kirby and the Amazing Mirror to show what new palette you would be getting. However, at the last minute I realized that they weren't appearing when I built the binaries and I couldn't figure out why. I'm rather proud of them, an disappointed I couldn't get them working, but hopefully I'll figure it out soon.
