Escape a haunted maze, or run around being terrified a lot.
Depth of immersion is selectable in the game. Movement can be coupled to real walking (or running, as is likely to occur) for maximum immersion and scariness, or via head-tilting. The maze can also be viewed from above.
No ads or unnecessary permissions. No internet connection required. Gyroscope not required.
This application does require a functioning device compass, so the magnet in a Cardboard headset may need to be removed.
