So I just spent the last 8 or 9 hours plugging away at this, didn't even notice the time I spent on it.
This is done with the Pico-8 palette (and was intended to be used with Pico-8) except I made a bunch of 16x16 tiles and didn't realize it had a smaller resolution that I would have had to use instead. Oh well.
My goal was to take a bunch of Super Metroid-themed areas and demake them with a simpler palette/resolution, and I think it turned out pretty good. Ultimately, I just wanted to make something that people could use for a jam or whatever. How many sheets/areas like this do you think it would take to justify charging $2 for it?
