I am not as high on the game as he is. Aiming with the sticks is a little loose do to the momentum they add. Boss fights, minus the last one, are non events. Level design is good, but it is easy to get lost (would like a mini-map).
I do think the gun level up mechanic instead of ammo is a great system.
