I love the art style and all the unique enemies you spawned in this game. The enemies felt like they became really overwhelming, really fast - so I was running away from a mob 100% of the time, which was pretty entertaining.
My main feedback would be to introduce some kind of weapon or skill that allows the main character to kill a large number of enemies in timed bursts, to give the player some form of enemy crowd control. I think having the feeling of frantically running away is great, as long as you occasionally provide a way for the player to deal with the enemies, so the player feels like they can cheat death if they're clever.
Overall, nice work! I had fun!
