Nine Hours, Nine Persons, Nine Doors

• There are multiple endings. After finishing the game for the first time, you can replay it and optionally skip all the dialog from previous playthroughs.

• In the puzzles, sometimes you have to click multiple times on the same object/surface to get different or definitive answers.

• The way you interact with another person to show him an object is to go to the room he/she is, open the item view and click the "Search" button. The other character will tell you his/her opinion about the object.

• You can save the game at any moment, even in the middle of a dialog.
