Fantastic

Hey good job, your particles were awesome. The graphics seemed consistent... and the explosions were smooth. You should try to make an original instead of a COD 2D game... Don't get me wrong a remake is always a good way to get your name out there, but now that it is... go for an original.
Also if ya need some help making sprites/graphics, I'd be glad to help ya. But overall one of the best mini games I've played in a while.
Ice level was a bit hard, I couldn't jump sometimes, maybe because the block were breaking? I would suggest perhaps adding a bit more time before they break. The graphics could also use some work. Also I would've made boundaries, because the first level I kept running out of the room on accident... and having the game restart the level. Other than that it was pretty good.

An extra note: Captain Price was prisoner 627 not 687...
