If one word describes Twisted Pixel's games thus far (The Maw, 'Splosion Man), it's character. Sure, the gameplay -- especially in 'Splosion Man -- is certainly more than adequate, but "Everybody Loves Donuts" and adorable little scamps who can only say "Mawwwwwwww" are really what I've taken from TP's games thus far. And, from what I played of Comic Jumper's E3 2010 build, it seems that the developer plans on continuing in this tradition with Captain Smiley, his partner Star, and the many, many characters littered throughout the game's multiple comic styles.
Which isn't to say that, you know, actually playing the game isn't a blast -- it is! At its heart, Comic Jumper is a 2D side-scroller --that said, in typical TP style, variants abound. The game quickly jumps from side-scrolling to lightgun shooting to on-rails action, intuitively adjusting the controls as it goes. Was it occasionally frustrating? Sure, but I'll allow the occasional frustration for all the yucks.
