Labyrinthe risqué

 
You are in a maze. Your task is to find the key and then exit. On the way you will come across obstacles that remove the points of life. You have a few stones. When used they are visible on the minimap. You can restore the points of life and replenish the supply of stones with the help of a chest. Some chests are locked and you can open them with the key or a stone. If a stone was used for the opening, it will disappear.
