Well, this game was short but nice.
In my humble opinion, this game is not as good as the other commenters make it out to be. Anyone reading the comments would get a false sense of the game before playing it.
I didn't get attached to any of the characters. The story and game was short and fast, I didn't get a sense for the timescale and the game didn't show it. One moment Dex goes off the ship and the next He and Seren are on a mission. Didn't get to see what else Dex and the Operator do in their lives when they aren't in the ship and talking with Seren. I didn't get to know any of the characters or relate to them. If they are in trouble or something bad happens to them I just don't feel sad for their fates.
As for the bad endings, I checked out every single one of them and it was kinda "meh". Didn't get to see or know anything about Seren or that stranger who claims to have created Seren. Everything is so vague and leaves me with a bored and dissatisfied feeling when I get the romantic good ending with Seren and Dex.
