Finish the game and start a New Game + adventure. In that mode, you can enter the following button combination any time you like to start flying: UP, UP, UP, UP + A.

Once you beat Fez (with any number of cubes), you can select "New Game +" from the main menu. In this mode you retain your cubes, maps, keys and previously unlocked regions, but you also gain an additional skill. You will get sunglasses at the start of the New Game + that allow you to view the world in first-person.

Unlockable	How to unlock
First-Person View	Return to the Hexahedron in New Game+.
New Game +	Complete the Game.

First, make sure that you collect all 64 cubes. Once you have done that, head to the Star Gate in the 32-cube room for a new ending. Once the credits roll, select New Game+ again from the main menu. Play until you reach the point where previously you received the fez and the sunglasses. This time, you'll receive a pair of stereoscopic 3D glasses, which automatically enable Stereoscopic Mode. You can disable the effect in the Settings menu, if you wish.
