Hello, I think so far the game looks pretty cool. I like how you can upgrade your boat when you collect treasure which also gives you better cannon balls to shoot.  So far, the only bug I could find is that if you sail too close to the edge of the map, you may fall over or off the map. Other than that, everything works fine. Some ideas that I have are could be like adding rocks and obstacles in the ocean or maybe a whirlpool. Maybe there could be sharks, but its just an idea out there.
