The graphics of the game are very nice. It's impressive that you wrote your own javaScript-based engine for it.
At the beginning, the first ship is a bit too slow, but later on, managing several ships requires a lot of attention. It's a bit confusing that it's too easy to accidentally drive the ship behind a city and then you can no longer select it.
I might have broken the game by the end. I think I got all the raw materials and gold, but there was no endgame.
So I hit the lighthouse with all my ships.
Anyway, it was so much fun!
