Not only does the game hit some great, intense moments of action, but the gameplay and mechanics stay smooth throughout the experience. The only problem is after you hit level 40, theres really nothing to do. In order for the game to hit its price point, I would have liked to see something like a survival mode where you fight waves of enemys, or a co-op mode with freinds. Multiplayer never really works well on iOS, but if they could nail it I would be totally satisfied.
All in all the game is alarmingly addicting. The only changes I could think of would be either a lowered price, or added game modes.
