Help me understand Kramnik's Round 5 at the Alekhine Memorial

I had someone tell me that Vladmir Kramnik was "taking risks" and exploring "new ways to play the game" of chess in his less than stellar performance in round 5 of the 2013 Alekhine Memorial.  But it seems to me that he didn't really feel up to playing that round and just pushed wood, as they say.  It seems that almost immediately he was under major attack and not only never recovered, but seemed to make matters worse on each move.

I know I'm unqualified to seriously analyze his games, but the mistakes made seemed elementary.  Someone please help me understand why he seemed uninterested in developing his pieces or castling.  What was his plan?  I can't see it.  This looks like a game I might have played, and I'm unwilling to accept that.
