Gold And Diamond Treasure Escape

Assume you live in a small town next to the ocean. One day after the school you set out with your friends to play treasure search in a deserted fishing house on the shore. You were fumbling among the old furniture of the building when suddenly you glanced a lid which opened must have led somewhere. You opened it and found a box laying on the bottom of the basement. You grabbed it and lifted it up. You were amazed when you opened it because it revealed a fortune. But in the meantime you heard a door slammed. When you were about to leave the place you found this door locked. Find hidden objects and solve puzzles to get out.
