The concept of the game is amazing. To me, it is more like a art piece instead of a game. I would say just wondering in the building and trying to find your partner is great itself, although i felt anxious when i see people just keep missing each other. But I think that is also part of the game. If you don't like this part, it may be great to use some light music and create a more comfortable scene to ease this anxiety. And the last thing, because i cannot play it by myself, i still have the question of weather they can really meet each other in the end?
