Cool concept and fun to play for the first 30 minutes or so. Annoying to have to wait to get the gun shop and find nothing of use over and over again. I stuck it out and finally bought the $10,000 machine gun only to find that the $1,000 one that I bought near the beginning was way better. Very repetitive with no payoff after about the first 25 levels. It's literally the same thing over and over with new outfits. The guns don't get any better and every level is super easy.
