This game is very simple, almost like an idle game, but somehow it transfixed me. I would get excited every time I saw a big cluster of fat, juicy rabbits just waiting for my talons.
I particularly liked the animation (love the twitching rabbit ears!) and the sound effects, although you might want to consider randomly varying the pitch a bit.
Also, the stretches that go by without encountering anything feel excessive.
Lastly, the game feels like it is missing some sort of threat or obstacle.
