Game is stuck on the loading bar for me, which given the other reviews, is a bit of a disappointment.
Edit: Okay it loaded on me and I seem to have missed the point of playing monotonous levels over and over again in order to unlock the necessary levels to advance in the game. Grinding for the purpose of making your game longer has to be one of the the worst inventions mankind has ever produced. Also, chill out on the main menu and features. It took me literally half an hour to discover how to operate the launch sequence and advance to what I think is the main game.
