Really nice looking game. I like the glow effects around the fire and time. Its a cool idea to have the time remaining as part of the level instead of showing it in the UI (I think you could probably get away with removing the timer above the player).
The platforming was a little difficult for me. A few "cheats" that platforming games sometimes use are making hazard hitboxes smaller than the sprite and giving the player an extra second to jump when walking off a platform (coyote time). I think if you added those the game would feel a bit easier.
I liked the idea of curses punishing you for using the usual controls. It was surprisingly tricky for me to stop moving left when aiming while jumping. The no jump level was my favourite - the spring mechanic is good (just needs a nice "boing" sound).
