Marie's Room has a total of 7 Steam achievements, all can be earned in one playthrough taking about 20 minutes, 5 achievements are earned through natural progression and 2 which require you to interact with all objects which are missable.

The following achievements are listed in the order that you should earn them.

Be aware that a few people are reporting that the "The complete picture" achievement is not unlocking for them despite interacting with all the story related object in the list below.

Steam user 【=◈︿◈=】 had this problem and advised "I found that by rotating the objects when you examine them you manage to bypass that bug, or at least that's how it worked for me, and also for the guys at the other guide". So if you are one of the unfortunate few not to have "The complete picture" unlock first time around give this tip a try.

* = Journal entry object.
no star = Story object.
