Yeah, ditto. I'm tied for fourth with 203.3%. Lots of messages = DI started getting a lot of messages on XBL, even though my friends list is almost empty and I haven't turned my console on for a year before playing FEZ.
Thought that was weird until someone asked my how I am 8th on the leaderboard with 200%.
I'm not even sure how that's possible, I still only have 31 anti-cubes. Seems bugged?
You can't solve those things until you've beaten the game.
And if you already did:
Look at the floor in the vincinity of the pillars.
The weird red cube you got in the observatory counts as another cube, which is giving you the extra cube needed to reach 200.0%.
Which rooms do you have yet to solve? I gotta get you to join the club.
