There's a pretty substantial disconnect between Mutant Mudds' vibrant appearance and its tough-as-nails gameplay. Or at least I didn't expect a game whose protagonist is a water gun-totin' kid named Max to be an unforgivingly difficult 2D platformer. My mistake, really. But it doesn't change the fact that it's a ton of fun. In fact, it's that very difficulty that makes it so much fun. Challenge junkies, this one's for you.
