Although I was really looking forward to playing this game, I have to say that I didn't like it as much as I expected. Without voices or sounds to simulate them, it gets quite heavy at times. Maybe it would be nice to play it in two or more sessions, so that doesn't happen.
Unless you want to get all the achievements, replaying it is not the best idea. Even then, you can't save or load and the only way is to replay the chapter the achievement was in, which means you may have to replay most of it to get to the exact part.
The ending wasn't the best, but it wasn't bad either.
