Interesting take on the theme. It needs some more polish, but it's still a nice game, well done!
I found the human very hard.

With polishing i mean animations, health systems, better difficulties, graphic/sound effects and so on. Not really important or necessary for a prototype, but something you can always improve, especially if you want to focus on an after-jam version. Putting these aside, it's a very nice game, well done!!
