I liked visuals, it gave off Baldi vibes for me. The lose button made me laugh the first time I pressed it. I also liked the parallax background, which I know are a pain to make it work correctly in Godot.
I was confused at first why nothing was happening at the beginning until I realized I had to wait to let the steam pressure build up, a faster build up time (or maybe have the train already starting) would have helped understand what was going on. Also some sort of win condition would have been great.
Good first attempt at a game jam, keep at it!
