This is a really cute game that I could see easily becoming a very fun mobile game. The difficulty curve was perfect, easy for the tutorial and then increasingly difficult without ever feeling unfair. I was able to survive until about 30s from the end when I got greedy and tried to move a trolley across the entire map to get a coin (since I had all of them up to that point) and ran face-first into it.
One thought I had is that it would be nice to be able to drag the trolley across multiple tracks at a time, directly following the cursor and snapping to the nearest track instead of having to swipe multiple times to get one across the map. That'd require some rebalancing, I'm sure, but I think it would make the game more enjoyable. Great submission!
