I have a couple of issues with this game...
1) it's just too hard. I've been playing for some time, I unlocked 50% of the awards and the rewards, and I still cannot beat the smallest nest. Very frustrating.
2) The weapons are pathetic. seriously. they dont last too long and given the fact that they're so hard to unlock, they should be more helpful. They're not.
3) high scores: there are two cats for high scores. there should be 6, for each mode and for every size of the nest.
