Hey, 

I am a little out of my depth when it comes to music and sound creation in pico8. 

If there are any developers interested in creating some music you can have full creative freedom. 

You can try out the game I posted it in the submissions or you can follow this link. https://buddyboybueno.itch.io/star-pico8

If you want to give any feedback on the game feel free to leave a comment on the game page. 

Thanks, BBB.
