If you didn't get all achievements after first completion of the game - do not worry. Using savegames you can return to these moments, when you can achieve the given achievement.
Once in the church, look for more than one solution to the problem. For example use the nail or clothes hanger to widen the wall joint, or extinguish the fire with water from the chalice or priest clothes or mop (chapter 1).
With perfect moves topple the statue in the church - Nina can't give you a hint about finding your rhythm (chapter 1).
Walk towards the light without turning around and open the door at the end of the corridor (chapter 7).
Walk at least 5000 meters in the game. It is not excessive requirement and probably everyone can get it.
Spend at least 500 minutes to finish the game. This achievement is rather difficult, because even when you examine all interactive objects and try all possible solutions of problems, you can spend with the game maximum 350 minutes. So I suggest leaving the started game until you get the achievement.
Examine locations, looking for interactive objects by using magnifying glass icon or SPACEBAR at least 2222 times.
Master always chooses more difficult way - solve game challenges (statue in the church, touch display on the ship and Santorin underwater maze) on the higher difficulty level.
8. The Brain
Ask the narrator for hints at least 150 times (exclamation/question mark icon).
What would be the world without love and friendship? Help Cassandra in Alcatraz (chapter 5) and save the Max instead the world on Santorin (chapter 8).
10. Party Animal
Ask everyone for the wedding. Do not help Cassandra in Alcatraz (chapter 5) and save Max on Santorin (chapter 8).
11. Good Samaritan
Help if anyone ask for. Help Cassandra in Alcatraz (chapter 5) and save the world instead of Max on Santorin (chapter 8).
What would the partnership without the world? Do not help Cassandra in Alcatraz (chapter 5) and save the world instead of Max on Santorin (chapter 8).
Check all game endings. Choices made in Alcatraz (whether to help Cassandra or not) and on Santorin (save Max or the world), affect the fate of characters, which you find after the game end. To obtain this achievement you'll have to reload your savegames (from chapter 5 and 8) before your key choices and select other variant. You also have to finish the game 3 more times.
