Hello Max Horror and thank you for testing the game ! I understand your feeling and some of us felt the same way as you experienced. We tested many settings for this tool and this was our final decision. Only few players seemed really disturbed by the flashlight as it is during our playtests sessions, which pointed out more important things to fix.
Since Horror seems to be your favorite genre, I'll keep this advice in mind if/when I'll go for another horror game. :)
