You have to piece the cube together, then find the missing letter pieces, have not got that far yet but im assuming the code will be in the letter?.
I got to the safe in the red room, but cant open it and cant be arsed going through all 9999 combinations. I tried the green room and managed to put some stuff on the cupboard thing and got the incence burning but dont have a clue what to do next.
Its strangely addictive though .
