I am so happy to have come across this! So much nostalgia! Also quick note, I noticed someone else mention this but in the current 1.3V it seems like that looking at Slenderman from any distance from 1-3 seconds ends your game. He also can teleport on top of you as well. I don't know if this is intentional but I figured I'd let you know. I'm so happy you have brought back this legendary game Marc Steene!
