[TOMT] [Game] [Website] Old browser game about surviving a plane crash on an island

I remember the website beeing in french(so i did not understand much as i did not know much french).
The game might have been called "(some number) miles of the coast" or something similar, in french.
The premise of the game was surviving a plane crash on this island. You could fish, hunt , gather materials, explore the plane wreck etc.
I remember there was a temple you could explore once a week or so?.
The game had some limited multiplayer elements like the early facebook games, but i do not think it was on facebook.
