This is a true revolution for HUD, the main menu interface, gameplay, lore, and level designs. It wasn't too hard for me to solve these puzzles, but in one chamber, I got stuck. If I remember correctly, it's number 16 where you could turn on/off electricity. Very good game. I wish to thank the entire team that created this masterpiece. Thank you for all you've done. See you in Aperture Moon Laboratories!
