Could you go into a bit more detail what you mean by:
" What would the point be? To have a safe bubble in which you as the player are ok with being scared!"
An example would be great to have!
Thank you for the question. And sorry up front for my incoherent explanation!
The idea here it to have safe tools presented in a way that they are actively incorporated into the story to allow the players to fully immersive experience.
As the game takes on a bit of a nightmare turned reality thing. I actually once used a semaphore to denote the Saftey Flower for the player ingame. All semaphores showed the exact colour of the support flower, thus making everyone aware that they can push their boundaries a bit more once the knew that the Saftey Flower was in place.
Does this explanation help?
Ok here's a bit of literature.
What I call a Saftey Flower apparently is a Support Flower!
