That was so fun! I was able to beat it.
This is a really cool idea, I thought it was a little too easy at the first level, but by the third it was a good amount of thinking and spinning. I could see it getting super complicated with future levels.
I was even able to do a trick shot by spinning the track right when a train was leaving to send it off at an angle directly to it's shed
Some things to add / thoughts:
The text countdown spun with the train (which I found funny but should probably stay right side up)
The choo choo sound got a little repetitive, so either adding another sound or changing the pitch randomly could help
There should probably be a penalty if the train hits another train or goes outside the map
