I thought this game was pretty good.
My main issue was that i thought the game was a bit to easy with some enemies like the sword users never got to hit me. The constant throbbing of the screen when nearly anything was happening started to hurting my head a bit and i wish i was able to turn it off. Also the shotgun felt a bit under whelming when compared to the other ammo using guns even at close range.
Other than that I though that the other enemies where fun to fight and the boss at the end was good!
