Great choice for colors and assets :) I would recommend to change hitboxes to better fit character’s sprite, and make sure enemies cannot hide behind the player’s sprite. Adding an invulnerability time after receiving damage would be great as well, because you can die near-instantly! It’s too bad because it prevents people from actually playing the game :p The boss came up too early in the gameloop so I never used the shop.

That + sounds would make it a really really cool game!

look really good, there is the reescaling of the pixel art, it's stand out a little, with  the short time of the jam is a expected issue, you could use a shader or filter that  round the image in general to hide it until you have the properly scaled pixel art(and left the shader as a  alt style in options, a easter egg , or a price).
With the concept and the limitation, sincerely the bowfire not have propource beyond being a switch to fight the boss making it redundant for the gameplay
I insteand whould start with bowfire on, make the boss appear when the bowfire is off,. shif thing to maintain the bowfire on, and instead make that each you use action it push the enemies out of the fire,  in a way you have to strategice  if is better to burn the wood and gain more time, or  push the limes out.

Fun little game with a great color palette! 

The color palette and the sprites are so cute and cozy, I almost forgot I'm slaying an adorable woodland frog with a sword.

The presentation was on point! Loved the art. The shop system was solid, too. Well done!
