It was weird to go through training in this. I KNEW it was way too easy. Wait, I was training to make a train? What a funny pairing of words! Anyway, this was surprisingly complicated. It got particularly annoying with how I had to use every train track.
I know that I could have made the train go through with some track left over. At least it was pretty clear cut. I'm stuck on the second level. I guess I'm just bad at puzzle games. Yeah, that explains a lot.
