Nice idea, poorly presented
I liked the idea of the people signing up for the army and stuff and them all getting blown up and stuff but you didnt present it well. I think if you remade this with some one else to help you this could be really good. You should try some1 who can improve those graphics and i think you might want to ask the voice actors to do those voices. Cos by the sounds of things your voice aint broken(mine either - im 13 :P)
I hope you take these things in mind and use them to the best of your potential.
Thanks for listening to my ideas!
