Escape Royal Beach House

Imagine you have been living in a town which is situated on the shore. One day your friends organized a party in the beach. They hired a house in order to make it more comfortable to those who want to sleep there. As you arrived the music was loud and everybody was dancing outside in the pool. When you felt tired you went inside and fell into sleep soon. The next day after you woke up you found the house empty. You shouted to learn if somebody was upstairs but no response came. You set out to leave but appallingly found the entrance locked. You picked your mobile to call for help but its battery was dead. Find hidden objects and solve puzzles to get out. Good luck and have fun!
