I genuinely have no idea how you are supposed to manage the track and fix things at the same time. Not saying it's bad, I enjoyed it a lot but I feel like it was meant for multiplayer and people managing different tasks than running back to the start of the train to change tracks with how fast it goes. I genuinely had no time to change tracks. Like, one person for managing the tracks, one for managing cargo and one for fixing things.
Gets a lot of points from me for genuinely putting the player in a floatie. Adorable.
