Let’s say that you bought the Monument Valley expansion Ida’s (RED) Dream back when it was available. What if you want to play the blue version now that it’s available to everyone? From Pocket Gamer:
If you were feeling charitable when Monument Valley‘s expansion Ida’s Dream was released as an IAP during the RED promotion and you’re concerned you can’t play the blue version now – fear not! You can play the blue version by following this simple workaround.
Switch your iOS device to flight mode then open up the game and hit ‘reset game progress’ in the main menu.
