You are my god...
That was great...the helicopter, the guns, everything! My only qualms were that the Airplane flight from battle to battle took FAR too long, and the Helicopter was overly powerful in easy and normal. Hard, however, was ungodly difficult. Maybe it needs to be easier.^^;
The music was still waay too quiet, with the sound effects way too loud, and that bothered me. Some ideas for the next one would be A Hummer, a Tank, and the ability to call in an Airstrike. You could have upgrades for Powerfox's Punching Glove too, and create a gun that freezes the enemy...
Great characters, animation, and style.
