Thanks for making a Let's Play, and thanks for giving Avian a shot! Be warned, the game is difficult and it will try to trick you, the game is really over when you get the credits screen. Regarding the cross stone puzzle, there is a hint in the room where you found the batteries, there is a note in one of the file cabinets which will help you solve the puzzle. Best of luck!
