Wow. This was an emotional roller coaster from start to finish.
I started with the non-romance/non-friendship ending (because I like to do things the wrong way around), and I have to admit that while it was good, it wasn't amazing. Then I worked my way through the friendship and romance paths (in that order) and my mind was totally blown. The complexity of the characters and their relationship was masterful, and I loved how they called into question what humanity really means. During the romance path, when Silas starts talking about how he never had a choice, I swear you could hear my heart breaking.
That was a long-winded way of saying that I loved this game and hope to play many more from its creators!
