Great but overkill on the birds.
Love this game. Definitely an upgrade over Chopper1. I play it quite a bit. My only gripe is that there are too many birds. Is the chopper flying around in an aviary? Seems the only difference in difficulty is more birds to dodge and one flock nearly takes the chopper down. Thats not fun. Add more tanks to kill, not more birds fly through.
