Perspective.
I'm sure there are many words you could use to describe this game, but "perspective" is what I keep coming back to.
This game is a puzzle in the almost too litereal sense of you are putting piece together. Scrambled memories which are given such a different meaning when you realize that it's not actually this person who said it, but that person. And it matters.
The unfortunate thing about this game is there is not much one can say without spoiling it. It starts well and ends with me in tears. Except for the number unlocking section. They could have done that a bit better.
Still. Play this.
