Escape Room OZ: Outback Hell

You are travelling in the Australian outback. You stop to help an old lady to change her flat tyre, and you accept her hospitality of a cup of tea at her house as her saying thank you for your assistance. But, the old shack she lives in is not just an old ladies house. You awake from a groggy sleep to find yourself awake but trapped. What has happened, and why can’t you get out of the room? What is that annoying ticking noise? Save your team from your own Outback Hell.
