Today's Lospec #pixel_dailies prompt was famous with a really fun and colorful palette -- https://lospec.com/palette-list/warm-36 -- started with something else, got frustrated, scrapped it, and made a tiny tileset/level mockup from a rather famous mushroom kingdom.
This happens every so often, when I try something that I'm just too tired/simply don't have the required skill to do. I'll go back to the original idea sometime, hopefully with more energy and more ability :)
