Arrrr...
Dang, this game is fun. Considering it's a button-masher and the graphics are...well...(although that's the point), I can't stop playing it. Music gets a little grating after a while, but hey, that's what the mute button is for.
A suggestion: Change the color of the "Special" bar before it reaches its fully-charged level; there's a lot of levels with white background which have exactly the same color as the bar's progress and it's impossible to tell its current level while standing by one of these backgrounds.
Also, kudos for House's and Colbert's specials. :)
