This game was super fun to play. I think moving the gun to the middle would be helpful. Right now you need to constantly look to the right side of your screen. I bet it would be even more annoying for players with large monitors. Maybe making it half transparent or just little more to the right side so you can still see the player. The game balance was quite good, but on my second attempt I had this op tactic where I didn't take any blood bullets and I took this item that makes you get +4 damage if you don't have bullets and won the whole game like that. Anyway very good work for a game jam, it even has the potential to become a full-fledged game :D
