Thanks for your detailed comment! Agreed on all points. The goal of the game is of course to make loops. We had planned on either crashing the train (score deduction) or disallowing starting the train, but in our rush to the finish, in the end, after submitting, we noticed we had neither system in! Oops. There was a plan to add a few tickets to incentivize crashing the train by removing the score penalty, but those ideas got cut because we were way behind schedule, and had to scope down.
Both jam games I've seen from you contain so much content, I don't know how you manage every time! And by yourself?! Haha.
I'll add your suggestions during the picking screen (an oversight), and an indicator for swapping the station. I think the station swapping thing was a last minute feature. And we'll change the color of the red tile. Good feedback! Thank you very much!
