The game was fun. I did get a bit confused about what was going on while playing the game, but I did easily manage to find everything.
I think I understand what the game is, but I might have at first confused myself after watching the ‘Unidentified’ video. The plane in which you are on during the intro is effectively limbo, while the airport you see is an amalgamation between your view of your destination, and pieces of your memories twisting together. In the game when we listen to the tapes we are listening to the player's life. This is why the airport looks completely charred, from the players perspective it is a loss of self, just like the character who can remember pieces but not perceive those memories as fully theirs.
On the plane you are losing yourself as you are passing on, the airport is just the representation of that moment of confusion and loss of self. At the end of the game we are seeing the same events that happened to you now happen to the next person.
It was a fun game, it did take me a little while and a few watches to truly grasp what I was playing and the visuals make a lot of sense why it seems such a mess and all charred when you think of the story.
