Katamari Damacy was never meant to be played with a keyboard ... I've played a lot of katamari but when I've tried to play Katamari Damacy Reroll with a keyboard, I absolutely hit a lot of wrong keys and I absolutely do terribly.
Thanks for all that good spot-on commentary though :) about the remake of the very first katamari game, a really good place to start. (I know a lot of the commentary was exaggerated ... just like a lot of the craziness is in the game.)
