Hello. Thanks again for the comments, everyone. I have been looking at the suggestions that have been presented and I think there will be a few updates to the game once the jam is over. Most of my work (lately) has been on the custom resource editor I used to help make this game. I noted a few weaknesses when trying to work with a greyscale palette, so I have been making some updates and improvements to it before anything else.
I would also like to an include an option to select from a number of pre-made palettes in the options page. Depending on your hardware performance, it may take a second or so to update the game since every pre-rendered sprite sheet has to be re-drawn with the updated palettes.
