Nice! Quite a lot here for a jam! Here are things I noticed as I played:
- The movement is very slide-y
- The embedded web view crops out a lot. That's something you can edit with itch's settings
- When enemies are on small platforms they can quickly flip left-right and it looks like they're bugging out
- I think the character has friction with the terrain when moving vertically, so it can make it harder to jump up tall gaps
- I didn't know I could wall jump until later. Did I miss an instruction?
- Once I got the fire power, I couldn't figure out where to use it to progress. I expected it to defrost the frozen tree near the start.
