Well...
many negative responses here. I guess thats because u are making money with this game. Cause at least the game isnt so bad. There are several more badly games here on Newgrounds with positively answers.
You did good work to the physics. The game is very smooth also the animations. Nice work. The idea with the weapon-switch isnt so good. It would be better to have both weapons (or maybe more?). The granades are crap, i couldnt hit a thing with them. The girl is atractive and does some cool moves. But thats all, The rest need some work...Like the Music, the track is cool, but its the same loop over and over. And that sucks. The game need some power ups, a bit more weapons, alternating enemies and some different locations...then it would be a good game.
