Thanks Sam!

Ah, yes, that's something we are experimenting with now. It's currently best to play it with mouse/touch, but it works well with a keyboard too. You can kind of compare it with a rhythm game, where you need to press buttons in a certain order and get the timing right. You kind of do the same thing here but just with trains instead, so we are trying to get that feeling with a controller, e.g. Left/Right trigger buttons sends vertical trains, while U and O buttons send horizontal trains. After you get a feeling of which button sends which train, it currently works pretty well.
