It's amazing how this game shows the exact same problems that Castle Crashers had in terms of excessively narrow planes that render the special worthless, enemies that can attack over a much longer distance and in the middle of a combo (the second of which is inexcusable in a beat-em-up), and a desperate hope that no one will notice the bad game underneath the above-average animation. Way to not learn anything from others' mistakes.
The idiotic self-referential humor is incredibly irritating, too.
There is no level variety, all the guns are identical in their handling and vary only in power and rate of fire, and the combat is incredibly repetitive and dull.
So no. There's a lot to complain about in this game.
Everyone complaining about the graphics is completely missing the point of the presentation although I suppose that expecting anyone under the age of 20 or so to get it is a bit much. Fun gameplay, fun presentation, 4/5.
