Hey, you can find the music and more here: https://earlyaccessdigital.bandcamp.com I will credit the artist on this page as well since now he's only mentioned on the submission page, big omission on my part.
I designed the background only for falling and later on when I made the levels go pretty high it didn't scale really well, maybe I should have made it a bit darker or a bit less moving, I'll try both variants.
Plan was to have the story before the first cassette but forgot in the chaos of the last day, will add it as a slide after the jam.
Thank you for all your feedback, I 3000% appreciate it!
