The game looks really good, it was fun, and it seems like it could have a lot of potential, though I had a few problems with the game:
1. It was unclear when you hit the boss, or when the boss hit the player.
This could be fixed by making a more obvious sound for when the player gets hit and having some sort of screen effect, and making the boss have a health bar instead of a health text box would make it so you see the health bar go down instead of a small number in the bottom of the screen
2. The screen is very cluttered.
This could be fixed by making the game either third person or a top down game. The game seems like it would be much more fitting that way.
3. Calling a projectile weapon a sword doesn't really work.
I thought I had to be right next to the boss in order to hit them with a weapon called a sword, so I did not use it my first run due to the bosses never being within what I thought was melee range. Calling it anything other than a sword would fix this I think.
If these things were fixed, I could say this was one of the best games in the jam, though these three things made it not as good of an experience for me.
