HMU if anyone wants some music!  Here's some stuff I did on the Pico-8: https://soundcloud.com/john-m-603708856/sets/red-planet-iv

Great work! I also saw your post in pico-8 server. If you are looking for collab, discord is a great place to go. Though I found pico-8 guys tend to do jams alone, collab should also be encouraged! It's better that you have an idea for yourself so it's easier to find a team that fits. Good luck!
