Battle Sprites
The pallette limitations on battle sprites are a lot less restrictive than overworld sprites - you can use ANY pallete as long as it's 15 colors + 1 transparent color. CoilSnake actually grabs the data from the PNG file this time!
The first color in the pallete is always used as the transparent color, so make sure you don't use it for anything other than transparency! Note the distinctive bright green color in the below example.
Valid canvas sizes are (0, 0), (32, 32), (64, 32), (32, 64), (64, 64), (128, 64), and (128, 128).
