Nice little infinite monster game. I like that the first powerup unlocks after you level up the first time - especially with the new enemy drop. I did find it a little hard to balance my speed, the enemy speed, and the length of my attack (it felt hard to get close enough to do damage without taking damage - maybe a wider reach on the weapons would have helped me to feel more comfortable in it, especially when starting out?).
Nice character design, and I like that the blue experience bar is the same color to make it super clear that it's my experience going up. It made me feel more tied to my progress, just by the color connecting the bar with my character. A small thing that I hadn't considered in other infinite-monster-style games, but I think it adds a little something nice here.
