I got Art Style Cubello, and its very addictive. Its like the 3D Metroid level in Tetris DS, though more evolved. Its DEFINITELY worth $6, as you will play it for hours and hours on end. It got like 1-2 bugs, but nothing that will kill your games (mostly, it doesn't spin fast enough sometimes, forcing you to place a block in a place you don't want to in order to make it flip).
But its the bestthing I have gotten on WiiWare yet.
