Pretty good execution for an automated game. I didn't get that far into the levels, but in the very first one seems to me there was no way for the train to just loops around a few stations and deliver passengers without your interactions with the tracks. In that sense it's kinda hard for me to put what kind of genre this goes to since it can't quite be an idle with all the required constant interactions, Yet for an active game I feel there's too little going on, or the things that goes on is takes a long time between them. It could feel quite chill, but for me it borders on boredom.
Another minus for me is the visuals. White quite cute, it was not possible to see the whole map and still able to read the important information, like what kind of passengers are waiting at each stations, without having to constantly zooming in and out.
