Good tie into the theme, challenging mechanics, and a solid foundation to continue to build on.
One thing I learned during this jam is that there are lots of QoL "features" in popular games we all play that we take for granted, like the second where you float and have a chance to get a jump off before you plummet to your death. I think it's referred to as the "coyote time" phenomenon. Likewise, I think a little leeway on the transitions between abilities would go a long way with players.
Congrats on the fantastic submission.
