Earlier quoted context omitted.
It's neat, but I'm not entirely sure what the animations contribute. What's neat about games like RollerCoaster Tycoon is watching this entire map full of things happening without needing to be controlled, but this doesn't really have that. There's your vehicle moving around, and there's people wandering around, but they're not doing anything. It doesn't feel like a factory of connected components.
I had the same feeling. I think it would click more if the cart visibly changed after each station — add a layer, change color, get cut into dies, etc. Then the animation would be doing some of the explaining instead of mostly being scenery.
I added just that! Thanks for the feedback!
