@Meko Guy does B count? I figured since B is a character and not an actual block placed down, he's not part of the cube
@Azza - B counts in my levels as without B, or Rs or balls, there would be no level. Another way to look at it is, can you take this entire level and fit it into a space that is only 2x2x2? Other designers have made levels and they didn't count the metal blocks that when pass the water mark so their levels were much larger than they claimed.
