Escape the Castle - Room 5

Notice the shovel, hammer and mace hanging in front of you. Pick up all three items and move to the barrel on the left of the screen. Use the hammer to pull out the nails from the barrel. Pick up the golden relic from here. Now go back to top of the stairs in the previous room. Next to the lit torch, you will see a symbol on the wall. Use the mace to break the stone wall and obtain a key and another golden relic from here. Next, you need to go up the stairs and unlock the door next to the stairs. This room is filled with sand. Use the shovel to clear it and obtain a key. Having obtained the key, you need to come back out and unlock the cabinet next to the door to acquire the Blue book. Next, tap the Blue book in your inventory and attain the last golden relic. Now tap the right arrow button to find the door. Tap on the door to open it and exit this room.
