I'm impressed by how much you achieved graphically with the different fades and the darkness, good job! It's obvious you care deeply about presentation. Modifying the sprites for the joint running animation was such a sweet little touch 👌
I think for the platforming you might check out adding some more polish to the mechanics by adding coyote jumping. And the whole cutscene being replayed after dying to the flames would be better made skippable, though I do understand that's the level scene you're reloading!
This may also be my favorite credits screen in this jam, I really loved how you went showing the credits in a super chill yet interactive format.
