You can and should ignore the extra palettes - they are a result of your choice of emulation, not the submitter's intent to circumnavigate the rules. More specifically, the game is an actual .gb ROM, so it is well within the limits of gameboy-like, and the default is a four colour palette.

Please also be nicer in your comments. It's not reasonable to suggest anyone "go quicker" to add music to their jam entry. The jam should be a relaxed way to feel out a concept.
