The game would be better if there is a menu with the start button and how to play because I was waiting for the game to start until I noticed it had and I was ment to control the ship.
Each of the islands could have been alot longer but I do think this game could have been alot better.

i literally left this tab open for 45 minutes and it still hadnt loaded the game

It's a good start. It's fun, but you should connect each island a little bit more.

There isn't much in this game to be honest.
3 islands to start out with, in which one island with is literally passive with just 2 jumps and you reach the treasure.
It is too straight forward.
You could start of by increasing the size of the screen, it looked too small for me.
Hardly you could see how the treasure looked like or the character.
I suggest you add in some sound too.
Good Luck further !

First of all, either make treasure not appear again after player collects it or make a counter, which shows how many treasure you collected. Or do both of these things.
Secondly, make a check mark to appear above an island on which treasure has been collected and make an ending (at least print "you've won").
Thirdly, make more islands.

That would make your game much better. (If after you would want to make game even more better - you could create a shop with upgrades; other pirates/sailors, to fight with/to cooperate with; etc.)

P.S. There is also some white zone in the east you should get rid of.
