It's a good game, but it needs a smoother introduction to game mechanics. Start with just 1 enemy so people can figure out how to kill without clawing for their dear lives. Some audio feedback would have been nice, so I can register with other senses if I have been hit or if I hit someone. You can use "BFXR
or some other random SFX generator for these effects, takes 10 minutes to set them up.
