i'd recommend having a timer and kill counter during gameplay, it wasn't really clear what i was "working towards" until i died, and seeing my progress increase as i go would be pretty cool. maybe also try to indicate what the health and attack pickups do more clearly. i think something cool would be to ramp up the difficulty as the game progresses. still a fun game though, i enjoy kiting around enemies like that!

Actually pretty good! Hope the game gets accepted :D
