I'm using the PICO-8 to make a demake of No Man's Sky. I've posted a couple videos of my progress so far, several tweets with pictures about it (here's a bunch of them embedded on an otherwise empty page), and the source is actually available on GitHub (though it is currently unlicensed, so ask me if you want to use part of it).

I'm looking for someone who can help me capture the feel of No Man's Sky in music and art within the limits of the PICO-8. I'd like to have several samples of music I can dynamically combine in various ways procedurally, and a few biomes I can use with art, and ships, characters, space stations, items, plants, animals. I'm not 100% sure what I need or want, but you can get an idea from my most recent video showing it:
