A Change of Heart
Cracked the code of the case
The case under the nightstand beside the bed. The combination is 3 - 4 - 9 - 5 - 1
Note: doing this will get you out off the room with almost all of the collectible items, do this as a last thing after you've gotten everything
Finished 'Marie's Room'
After you pick up the phone in the end, pick up the journal and walk downstairs
Every Word & The Complete Picture
The last two achievements require you to inspect every item in the room. These include the items outside the room (ex. wine book, pictures & temperature monitor).
Some of the most hard to notice are:
- Beer bottle (behind the courtain)
- The keys (beside the door)
- The basket on the shelf
- Broken window behind the laptop
- The paper pamphlet on the door
