Thank you. But why did you play for a long time? You can speed run the game in maybe 2 minutes :D (if you made the game and know exactly what to do ;) ).
But we're happy that other players get a longer and still enjoyable playtime out of it.
I think I focused on trying to max out the ship upgrades and the docks and industry on every city, so I tended to try and get gold more than explore for the city. My discovery of the later islands took a longer time for some reason. Maybe a faster gold progression would have made it take less time but still allow me to max out everything. I also was maxed out for a bit but due to the way I navigated around had runs where I died before exploring the map fully
