I really like this, thanks for sharing! The art style is distinct and really works with the concept.
As you've asked for some feedback, some things I am noticing after playing for a while - the economy is unpredictable and takes some figuring out - ie the cultures don't seem to make much sense with the products they make, ie. the jazzy music didn't make much sense for the demand and production.
I noticed there are multiple currencies, but not much motivation to explore one once you have dealt with the other
Fishing was more lucrative than I thought, and at the same time took longer to do than expected. Suggestion - make a 3 stage timed action to make fishing more engaging while taking the same amount of time
Some things I'd like to see in a future sense:
- ship customization, change colour or purchase new designs
- more information on what something is before purchasing - ie. a separate section for upgrades and tools
- Conflict - there is a notable absence of conflict, bandits are mentioned but don't show up
All together I really enjoyed this!
