Wow this was much harder than I expected 😅 The animations are gorgeous, that goes without saying probably. Gameplay works pretty well, all the pieces are there. The difficulty curve could use some tweaks, to make the start a bit easier. And also, if you have multiple trains, maybe the game could remove those trains when derailed instead of instafailing?
This first vulture appeared right after the "workers cannot fight enemies" hint, so it took me a moment to notice that I can scare them off.
The game was very well put together on the audio side as well, nice work there!
