These represent the three sizes of cube zones seen on the map.
Fez locked doors.
To access everything in the lighthouse area you will need to have lowered the water and acquired the first person ability.
Go through the door that.
I found a room with about 50 doors arranged in four rows of four on each side of the cube but with some removed blocked.
You can still solve the puzzle without having the first person glasses.
Looking for more help with fez.
Fez is a huge open world game with many many different areas very few of which are named or numbered in the game.
Every door i have gone through has brought me to a different door in the same room but the world map shows that there is an exit to another room.
Small medium and big.
You ll notice next to each stage name there is either an s m or b in brackets.
