Thank you very much for your input!
The lack of feedback in the game, like what you mentioned with the mines/lumber shacks, has been really bothering me since release, since stuff like the resource depletion was added last minute to balance the game better.
So I can't wait to get these things fixed, once the game jam is over.
The idea of having a notification for incoming pirates is a very good idea, I'll definitely look into doing that.
The pirates are actually supposed to naturally ramp up in difficulty over time in the game, but I probably broke it in the updated version and didn't notice, much like how I didn't notice that the game's window still has the dumb name that I originally gave it.
I also agree with you on being able to put individual resources into your ship, I'll have to look into the best way of doing that, while still keeping the UI as simple as it is.
I'm glad you enjoyed the game! And I really appreciate the advice and ideas. Thank you.
