Wow, this reminds me of one very old game called Vlak (Train). I have no idea, if it's known outside of the Czech Republic. The gameplay is essentially the same but you control the train. :)
Good game, but the levels were to easy for me. Adding more challanging levels would be cool.
I am adding link to the web port of the mentioned game. The web is in the czech, but you will figure out what to do :) https://www.retrogames.cz/play_487-DOS.php
