I would be interested in this, but not quite sure exactly how it would work. Would it just be one category ignoring height and level? If so, then it's basically just a race to 25 (21 w/ tetris start) lines, which still wouldn't be terrible. The appeal I see is that this is the fastest part of the game, so if people did decide to run it, it's easy to hop in and do a bunch of runs. You can also use the height to have an automatically generated platform for building high.

I may be too new, but I would be willing to help moderate, as well as running myself.
