I'm sorry for all the problems and the flashlight system was made in a very simple way because I am a beginner developer and needed to do very fast, I will try to follow your tips. And as answer to you question the only way to escape the monster is running away, I recommend use the areas where he cant see you.
I am so much happy you enjoyed the game because was to hard make that fast
(Sorry I make you wait the answer because I was in a trip)
(I will try your game)
