WOW, this is a really great game, idk how you did it, but while I was playing I thought I would have liked to move a lil faster and then you had the speed increase and then I thought the shooting was a lil slow and then you had the fire rate increase. I felt like you read my mind XD.
Honestly cant say anything to improve about the game, plays great, looks great. Super Awesome and super Addicting!
