Thanks a lot for the honest and detailed feedback! Really appreciate it!
You're right about the notes! They change based on how many ships you lost that night, not which ones. And yeah, the more you mess up, the darker the notes get. :)
Balancing the oil was actually something I struggled with quite a bit. I wanted to prevent players from just spamming Flash to win the game, but at the same time, if you don't use it much, you end up with plenty of oil left. Still something I could improve!
Btw, did you manage to finish the game? And what did you think of the story?
