Ooh, this is a really cool spin on the idea! When the theme was announced, we were also contemplating to interpret the theme as "built something using musical scales", but didn't exactly figure out a good game mechanic with that idea, glad someone else figured something out. I love how a track slowly evolves over time and it's nice that the levels allow for a bit of artistic freedom. Character movement seems a little weird and towards the end of the second level I broke it by accidentally recording a note on my previous playthrough that I think messed up any chances of escaping. Would be neat if the characters also moved on time, but I can see that becoming tricky with the climbing mechanics. Overall, I love the concept and would love if you continued working on this after the jam, I think there's a lot of potential still in here. Great job!
