Shame that the game's broken, I found the rest of it very fun (even though my brain kept pressing the switch instrument keys when I don't mean to lol). The story's very relatable too.
Thank you so much! I found the problem (I accidentally had 2 of the object that allows you to swap instruments present at the same time, so it swapped and swapped back in the same frame) so when the voting is over I'll be uploading the repaired version!
