The work and love that goes into this game makes no sense... it's impressive.
For me the most important thing about this game is the story it tells, it's beautiful and at the same time masterfully presented. Technically I love it, I'm not a fan of using AI in video games but I have to say that in this case it's perfectly implemented.
If we also take into account the background of the story I find it impressive, the emotional effort to create something like this is enviable.
Great work.
(And I'm sorry for your loss)
