I think the overall concept is solid, but needs a lot more workshopping to get an engaging game out of it. The biggest issue is the player doesn't have much to do. Either the train needs to move much faster, or the player needs to have other actions to take along the journey to fill the time. The sound effects got repetitive easily, and were quite loud, so some audio balancing work would be nice. Overall, it's the foundations for a nice game, but it just isn't quite there yet.
