I played through it twice, once picking the choices I felt were best, and once picking the opposite of what I felt was best. In one version I got the Last Online ending, in the other the Disconnected ending.
Very interesting, and heavy, concept for a short game. It leaves a lot of unanswered questions in a good way.
On the other hand, since it's short (being a jam game and all) there isn't much time for emotional impacts to build.
The music and visuals chosen fit the atmosphere well! The highlight is certainly recreating direct messages on the monitor like a real conversation would go even though it's with an evil ghost, maybe.
