This just in!
I came up with more additions!
The second level of Inscius Memoriam by BrawlerEX will be added to the WITBLO12 list as a stand-alone example, a la Calamari Cove. UNLESS Brawler is able to bring the series to a sustainable conclusion, in which case the whole series will be in. FOR THIS, THOUGH, I NEED HIM TO FIX THE ENDING, WHICH INSTAKILLS.
I now confirm the first four levels of TTOTMC by Triple J (Quattom Outskirts, Entrance, Readying for the Finals and Obstacle Course 1) as a WITBLO12 entrant. It's a big addition, but this series is already blowing me away, so I want to add the training levels as one entrant. Maybe we'll see more of it in 2013!
Luminous Caverns by blackyoshi will be added, primarily because despite being a small play, the graphics are breathtaking and the gameplay fun. So why not?
Edit: LordFalcon will now officially pull in another left field untouched level with Twin Towers confirmed for the WITBLO12 lineup!
I'll be playing some of the 22nd LDC levels so when the winners are announced I know what they're like, and what left field lower placements could be added.
Further Edit: Beyond by Volcove is a definite in! One of the cleverest puzzlers I've encountered in my day! Goes to show that we have a fantastic independent field to match our contest-sponsored levels!
