(Spoiler maybe?)
I didn't think the game was going to be that emotionally intense when I saw the warning, but I still cried a the end of TJ's route, poor guy... (first route I finish, as well). Please take that comment as a second warning.
This game is amazing though, like really, really good, it's going into my favorites.
Currently midnight when writing this, so I better be going to bed, but let me ask first: should I do the other routes before playing the 2 other Echo games? I really need to know, I want to play absolutely everything.
