Some incorrect words
Some of the words aren't correct. Example "Finally", that you translated as "Finalement" but the correct form is "Enfin" Another one : "Since he died". The correct form in FR. is "depuis qu'il est mort" and not "depuis son mort"
I forgive you because French is extremely complicated. This is a good Flash, but you better practice more. On French AND on Flash. And... Make the characters human. Stick pirates are cool, but not for that kind of animation.
I look forward to a sequel, or even to a "new-and-improved" version. Bonne chance, tu en auras besoin.
