Yeah, I've never particuarly liked Klax either... great ad slogan, but the game's not one of the better blockdropping puzzle games of the time, really. It's okay, but there's better out there. As for the TG16 port, definitely looks good apart from the absence of a two player splitscreen mode. The NES and Genesis versions of Klax have splitscreen support, so it's too bad that the TG16 (and all the other ports, it seems) don't.
