An amazing submission for a 4 day jam. Really nice vibes and a nice balance between working at different scales. Track placement feels a little weird but is not hard to get used to and I imagine it was more a result of the short time-frame.
As a small suggestion if you work on the game after the jam, some sort of warning that a station is are about to overflow whilst in the scaled down toy mode would go a really long way. You kind of get really chill playing with the toy tracks that you forget the urgency of linking everything up quickly at the larger scale of things.
