A time travel game based on a simple principle: you build a playlist as long as the desired time of the game, start with the last song (and the last chapter of the story, which ends with a terrible catastrophe), then you rewind the playlist and go back in time to try to prevent this catastrophe. The rules of the game are maybe a bit too confusing or unclear, but in the end it doesn't matter, because with such a concept that can be explained in two minutes you can in my opinion produce very very nice games!
