Today was New WiiWare Download Game Day on the Wii’s Shopping Channel, and I bought this and Strong Bad Episode 3. Just in case I run out of Fallout 3 to play, or something.
I gave Cubello a bit of a go, and it seems quite nice. I think I need to fiddle with the brightness settings or something though, as the black and grey blocks are both black, and the white and light blue blocks look the same.
