This is a play-through video that show every stage of this experience from the beginning to end in user's perspective. For challenge-based immersion, we have three tasks that the users must complete. These tasks are completed through grab interactions and listening for sound cues. This enhances our challenge-based immersion by requiring users to endure and tackle these tasks before the experience is finished. There is no other way for the VR experience to finish unless all of the tasks are completed.
