I just played my first route on the game, straight to Flynn's one, then it hit me hard at the end, so fucking hard that I'm still shaking, a friend of mine is helping me overcome that, he loves horror and he did played the whole novel before me, so technically he is helping me get over with that bad feeling.
At this point I don't know if I have courage to play the other's routes to figure the whole big picture, because in horror stories there's no happy ending, just endings where the characters survive with some limbs missing, broken hearts or something.
So I guess that my friend will have to spoil every route for me, and since some comments says (devs kinda said that too? I'm not in the mood to look for right now..) that every route happens in cannon, and there's a multiverse for it that mixes everything together (something like that), I guess I can imagine, at least, that there's a unwrite route where everything went fine and everyone had a happy ending together, but this is unlikely to be made into a game since this is a horror story, but I guess if there was a short vn telling the good endings would be cool. (At least for me)
So yeah, that's it, Flynn route broke me too much to play it by myself again, well done Echo project! xD
