Who would even play this game ??

If you have chest pains stop playing. Good horror games raise your blood pressure to extremely high levels. Due to the perceived threats in the game that can be difficult to shrug off as "fake", your body triggers a fight or flight response which is what happens when something actually poses a threat to you in real life. It's no joke; you can suffer a heart attack from being in a state like this*, and being in this state for prolonged periods is capable of killing even the healthiest of people. And stress, short or long term alike, has zero health benefits and too much too soon is also capable of killing you (it's proven to cut life expectancy). So if you can't take it, please don't continue. For most people it's fine if you take regular breaks though.

*That is to say if you have an actual cardiovascular disease.
