This is the holiday season and so many tourists come here during this season. There are many awesome places to visit in this city called Venice and that is the reason people come here year after year. One of the most attractive locations to visit is the Underwater Dream Castle. A group of five tourists went to see the castle. After a while all of them returned except one. He is probably trapped inside there and it is impossible for him to escape without being helped by you. You should dive in and start looking for hints and objects that you can use intelligently to solve the puzzles and help the tourist come out.
