This is a very brief game with lovely art.
You are a noise conductor on a mouse train. On each screen, you progress by clicking the train button at the bottom, which gives a satisfying animation with acceleration.
The story is simple and linear, but I was intrigued by the station list and the restart button. The restart button let me play again and I realized that everything was different. I played for a while and tried to imagine explanations for what was going on, especially given the list of stations, and that was fun.
