I did't look at the tags of the game so I was learning everything about the relationship aspect along with Elise which was fantastic!
The game itself was entertaining (albeit sad) and the atmosphere build-up was great. There are enough hints thrown around to help the player figure some things in advance.
I was actually looking over the game files when I happened upon some interesting pictures, for example 'S's room'. It's probably just early concepts but it was fun to look at, especially since I have grown to love every single character : )
