Tbh, I don't really get what are you supposed to do there and how to "Win".
I'm going to the yellow mark and wait, but when the time for train to move is up, he either moves to other place or just displays game over, where you missed train.
And when you go to the train too closely, you just fall down.
And hey: if you've learned something, that's great :) Because jams are for it: Experimentation and learning new things, so if you learned more about the Unity UI system, that's great.
