Interesting little game! I liked the concept a lot, very creative. I agree with the other comments that it is really difficult; the dino initially always got hungry right when my money hit 20, but after a few times feeding him I just kept running out of money and so could never upgrade the box even once. I even tried letting him get a little upset thinking his anger would go back down once fed but it never seemed to go down. I think this game definitely has a lot of potential though! Good work :)
