This is pretty cool. Good job on the submission! I like the art style and the way the mechanics are implemented.
Have you experimented with a fix camera instead of something that scrolls (a camera like Celeste that doesn't move until you reach the edge, than it moves to the next section)?
I feel like most of the time, I die because I don't know what's below and I can't react in time. So instead of being about platforming skills, it's about dying so you know where is the next platform. So I die, then I progress 1 platform lower, than I die again, then I progress 1 platform lower, etc.
Food for thoughts :) it's a great entry, I'm just giving a feedback!
Good job on your jam submission, pretty impressive!
