Le centre du château n'est pas encore la fin du jeu 🙂
Il te faudra ensuite visiter la zone avec fumée noire. Pour le passage des piques, j'ai pas trouvé comment le traverser perso.
Trouvé sur Gamefaqs :
In the huge room with all the Mushrooms and water at the bottom, exit in the lower left corner. Keep on traveling left until you find a huge room with spikes on the ground, covered in water. Access the pause menu and turn your Rahab soul off (this makes you able to float in the water, above the spikes). Float left until you hit a wall. Turn Rahab on again, and sink down. There's a small safe spot you can stand on here. Now, equip the Skeleton Ape soul so that you get the ability to throw further, then throw a Puppet to the other side of the wall, using the Puppet Master Soul. At the other side of the wall, turn Rahab back off to float further left. Head inside the passage in the absolute left end of the area, after passing all of the spikes.
Mais après, a priori y a une porte où il faut 666 pièces pour passer ^^
