The modelling and art are absolutely fantastic for a game made in 48 hours! Everything is so detailed, and it sells the fantasy mage setting super well. The running animation is especially well done; I appreciate the subtle difference between running and backpedalling. From a design perspective, enjoyed that the playing area grew over time to ramp up the difficulty and the use of the theme linking everyone's health as a resource.
My feedback is mostly around design. Running felt fantastic because it was fast and matched the pace of the combat and music, but the bullets were slow by comparison (by diagonally strafing I was almost going as fast as the bullets). Since the bullets were slow, it was hard to hit enemies without being rather close to them. I also never used the shield because I never felt like I was in danger, mostly because I could just outpace the bullets by running.
