21 deaths dude? That alone is better than any sniper montage, across the map kill, nuke, 42 kill streak, or a flawless guitar hero song on expert. That takes so much skill and hand-eye coordination it's crazy. You sir are the best video gamer I've ever seen!
I can get to level 26 with less than 30 deaths but I get stuck and give up they should make it so you can go back and redo or at least practice on level so you don't need to restart the game
