I gotta admit, lgb's retexture patch 'don't do this' is kind of silly. :V I do think the game is a little easier with the hitbox patch, though. I'd definitely encourage using it as you're learning the game, but I think you'd want to remove it as you move up to higher levels of play, it's an unnecessary crutch. Obviously there's no way to tell if someone's used it or not, so a rule about it doesn't have any huge bearing in the first place, but I'd encourage not using it for high scoring runs to make them that much more impressive.
