I feel like having more platforming elements such as a slide, or other parkourish moves would create a great dynamic with the shooting. Otherwise, you have a fine game right now.
I love the way you built the story. Your not the main character. The army is. All of the story is through a radio, which was very ingenious. My main complaint is that the characters personality seems to change from cool and calm to laughing and happy to delirious depending on what he says. He will say " IM NOT STOPPING!! IM NOT STOPPING!!!" , almost as if he was delirious if you see a heli, and at the same time he could say " LETS PLAY"! which sounds like he is having fun. Beside from that this game is incredible. 5/5 and faved. You sir deserve a cookie.
This is a perfect example of a difference game. Multiple paths, and the ability to skip or find all ten with some nice drawings and relaxing music to top it of, this game is incredible. 5/5 Just wish there was an ending with Robin Hood living with the girl happily ever after.
