The game is beautiful and atmospheric. I loved the music too. But there are no indicators as to what to do. I had to come read comments to figure it out. The first puzzle should be easy enough for the player to figure out or they might not want to keep going. An indicator to press space at the door, and the guide telling you to press Z would have solved all of that. As it was I was waiting for the shaking to stop to indicate that I was at the next stop, but it never stopped.
