Great art, but you can't leave out audio man. There is nice variety of enemies, but they all seem to do the same thing. The level pictured below was too difficult for me; way too many enemies. Do you which level it is? I wouldn't be able to tell you, because all the levels look pretty similar. Perhaps you can mix up the environment a bit. Maybe you can also make the healthbar a bit bigger and put it in the top left corner. Okay, that's all.
