Interesting concept and depth!
I don’t know what happened, but I think the game started misbehaving once it got to night time and it wouldn’t go back to normal. I was on DOSBox, maybe I should’ve just played it on the online emulator.
I'm surprised DOSBox made it that far. It breaks for me pretty much as soon as I pick my crew. The first line of description on the game page:
The download is also packaged with a custom emulator that plays it fluently.
