I really like the idea and the overall presentation of the game! The concept is fun, but I felt a bit confused about what each object does. A short explanation at the beginning or on the project page would help a lot, especially since the controls aren’t clearly indicated either.
It also wasn’t very clear how much gold you need before you can defeat the pirate. And regarding the secondary jam theme, I think it could have been explored a bit more deeply beyond simply having gold as part of the game.
Still, it’s a nice concept and I enjoyed giving it a try!
