Everyone's already commented most of the QoL things that I'd suggest, the one thing I could think of is just a visual of where the lava is going to appear before it spawns in. I have to agree with Verburner, I cam see the Baba is You inspiration, but it's clearly a unique game that stands on its own two feet.
A rhythm game where you can mess around with how you have to approach obstacles is a super creative idea and I had fun messing around with it. I also got stuck on the last level, but otherwise I had a really good time. Thanks so for making it and congrats on your jam entry.
