I usually write quite positive reviews but the only thing that is good in this game is the music. The complexity of the game mechanics is zero. Click as faster as you can until the dummy pirate "clicks" faster than you and you die...
I actually dont mind the art - it can be likable, but the game mechanics are just to simple.
I`m quite sure that the programmer is capable of much more. So good luck and keep improving!
There is a little inspiration if you want to check some pirate duel game:
