I encountered a game-breaking bug that wouldn't allow me to move the train, it was getting stuck in either reverse or forward mode, so it was impossible to continue without deleting the entire save file. It's decently good, I loved it, but there's clearly many bugs that need fixing first to make this as playable as possible.
I remember playing this bad boy back in 2007 when I was around 16 and Marsh Refinery spooked me with its maze-like layout and that thing chasing me down, guess the feeling hasn't changed much lol. Yes, there's bugs, I even had some funny ones happen, but I still recommend it despite its flaws. I recommend looking up PCGamingWiki for the "Windowed" section to make the UI look better on modern systems, as well as turning off Galaxy's overlay since that caused my game crashes at start.
