At first, I was concerned that the game was broken because my shots fired didn't seem to do anything to the enemies. But then I realized it takes multiple hits! I suspect that some feedback was missing and would suggest adding something to show players that the enemies are taking damage, such as holes appearing in their bodies, them recoiling from the blow and then continuing to come towards the fire, or a goo/blood splatter decal being added to the ground.
I also do not understand how this game fits the theme of the jam.
Regardless, great job making this game in so little time! The controls work well, and I really like the little bit of animation on the fire that we are meant to protect.
