I hadn't tried this game before. It seems pretty fun and, despite beating it twice, I think I'm yet to see every boss. The tongue-in-cheek tone is pretty funny as well.
The period near the end where all you have to do is wait seems a little questionable but I guess it makes more sense while playing with other people. Likewise, I would have liked to see crazier effects on items. They are useful when they drop but it's hard to get all that excited about a +2 regeneration ring when you are holding the +1 regeneration ring already.
