Does the All Parts category include specials?

And can I submit a run or is the category dead?

The wording seems to imply that you would need specials, but it also doesn't make any mention of specials. Considering the fact that the air duct takes 30 wins on any single track to get, it makes this category much more tedious to go for. Personally, I think the all parts category would be fine without specials, and a second category could be made to include specials. You might want to ask our mod, KeyKagimura, what he thinks though before you try a run.

Even though no one else (including me) has submitted a run for this category yet, I'd encourage you to give it a shot. It's always great to see more activity in this game.
