I almost cried with the ending. The artstyle and music direction are amazing, and create an incredible buildup for a crushing ending. 

I spent the whole journey thinking about potential twists, but I was not expecting what was coming. Certainly a work of art.

My only gripe is that the ending coments, after the story ends, sort of change the atmosphere too drastically after the final shock, I guess I'd space it just a couple more seconds, but I guess it's just a silly nitpick. 
It was an amazing experience!!
