Wanted to get this off my head.
Made on phaser, seems to work fine but not sure how it would work for long voyages on the Atlantic, would have to test with big maps.
Basically you can rotate your ship and the speed depends on the difference between the wind direction and your heading (needs some tweaks so that it’s not linear)
Also, wondered how the art would work on this top down view. Worked a second version using the current 8 directions pixel art and ocean animation (that one needs a bit of work but is much more at my grasp)
