One thing I try to do when I make games is try to make games without tutorials intentionally, trying to lead players to a goal through map design and leading visuals. I felt for the first half of the game I had achieved this but I believe I made a mistake by not having a light turn on in the hallway when plugging in the battery to the socket and I should have also had the socket more visible in the foreground to the camera. Thank you for giving it a play though, I'm glad you enjoyed it :)
