as a hat enthusiast and a rat, i sugest adding a classic top hat, you can't go wrong with that, or just put a rat on his head! It doubles as both a hat and a companion! :)
So how it works is, each hat has only one color but you can use a color wheel to adjust it. (This is what the normal sprite looks like without tint.) the sides are not visible bc they are white.
Guys, this will be the last couple hours before I stop taking acceptations. I literally haven't made like anything in the game except for the simplest Title screen.
