All achievements are fairly easy to obtain. The missable achievements (one in chapter 5, two in chapter 6, two in chapter 7, one in chapter 9) are quite easy to unlock if you're thorough with your inspecting. However if you miss them you can use chapter select to reply a chapter.

Achievements are presented in chronological order although due to the nature of the game it's possible to unlock them in a slightly different order depending on your decisions like which location visit first or which character talk to first.

*Note: It's possible more achievements are actually missable. These were the ones I found during my playthroughs.
