Ruined it with Game Center – Puzzle IO - Binary Sudoku Review

It was good until they force you into things you don't want to do. Bad move promoting me to login to Game Center every time I start the game. I don't want to have to tap other buttons and I don't want to login into anything either. Who really uses Game Center anyway? It's lame!
