I think I've entered the correct symbols (triangle, hangman's noose, backwards c and triangle), but it isn't working for me like I see it does for others in video walkthroughs on YouTube! What am I doing wrong? And the time on my clock isn't the same as I see in the walkthrough videos, but I can't change it a 2nd time. Please Help me with this! This is such an awesome game and I'm dying to go on.
