For everyone who gets the "Game Over" screen at level 200, reload your game in survival mode. I was shocked by the "Game Over" screen too but just went to see if I could load the game before I did level 200; couldn't but was given a survival mode option. (P.S. letting people know to reload their game in survival mode on the game over screen would be GREAT.)
