I like the concept of this game a lot. The balance of dealing damage and being in a position where you're defenseless and have to hunt down the arrow (which I wasn't able to pickup at one point, unfortunately) is really engaging and creates the right amount of tension for a battle with a big enemy. I think there are a few things that could use some tweaks, mainly movement and controls. You can survive infinitely by constantly moving in one direction, which isn't completely bad, but I think it could be a little more engaging. While it's probably outside the scope of a jam, adding attacks that either come out faster or track slightly, plus some sort of dodge option for the player (which you could limit via stamina, cooldown, etc.) could make a future version of this feel even better! I also think having the controls for aim and fire on the mouse is unnecessary, as the aiming is static. It could be accomplished even more comfortably on the keyboard, and would avoid having to reach across the keyboard with the left hand to operate the arrow keys while the right hand is on the mouse. All that in mind, it's a really cool entry! The art style and music is super charming, and the sense of scale is captured very well. I'd love to play a more fleshed out version of this boss fight in a full game using this style!
