This is a unique game that is fun and challenging. I think it's very clever of you to have the trees grow over time, it gives the game a realistic feel. Also +1 for funny title. I could see this doing very well as a smart phone application!
Not a big replay value for me though. Items would be helpful, like upgrading the teeth, slow down time, or add enamel to raise the bites bar.
Great game overall.
