It's pretty stupid, but not necessarily in a bad way. The level design is actually pretty good and the combat, while basic, is pretty satisfying; all the weapon variety you could ever want is here, and not a drop more. Also, the music has absolutely no right to be as good as it is.

I don't mind a game being goofy, but I think this one has just a toe over the line for me, and so some of it didn't land. It is undeniably fun, though...
