I really loved this game, and if I didn't have other games to rate, I definitely would spend way too much time on this one. One thing though is that if you didn't get a good kibble start, you would end up super poor and not be able to upgrade much, which eventually does snowball into the box getting harder, while you have barely anything to combat the increasing difficulty. But I did like the upgrades that were there, and it was fun to mess around with.
