in the first room where the first book is, there is a urn on the right it says i can open it and when i try it wont let me open it or break it. gold room opened up done. the platform room opened up done. the third room that has no book will not unlock. broke everything in every room in every coridore, interacted with everything in every room and I still cant get the door to open. i hope there is nothing wrong with the game and I am on level 20. too far to go all the way back. i hope there is someone that can help me figure this out.
