Thanks a lot, I’m glad you liked it and to be honest really surprised that you’ve actually completed it. Also, light doesn’t really attract him unless it is pointed directly at him.
I haven’t noticed the door that goes through the wall in your video but if I find it i will fix it.
I don’t know how but I haven’t noticed this speed-increasing exploit during the development but I am okay with it being in the game (actually too lazy to fix it).
