Minor Patch - Steam Deck Compatibility

I've been putting off controller support for some time, so have decided to release what I have to help out players that like to play on Steam Deck. This update adds a little bit of controller support, so players on Steam Deck or a gamepad should have a slightly more enjoyable experience. Also for Steam Deck / Linux users, I've fixed the 'Quit' buttons so it actually closes the game now instead of freezing up. For whatever reason, Unity doesn't like to close on Linux machines using the regular method of quitting the application, so I had to add a workaround.

There are also a few small additions, such as a small effect on your feet if you're currently standing in friendly paint. There may be some other small things I'm forgetting, but that's all for now!

Thanks for playing our game, have fun!
