Short cut to The Chamber Of Secrets:
If you make it through the various challeneges to reach the Chamber of Secrets, the narrator will mention as hidden passage to get back to the chamber without having to endure the challenges again. The 'Secert Passage' is found at the very first screen. Before the narration ends and you are automatically taken down the hallway, select your left arrow button to highlight the exit 'X', then press your UP arrow and a second 'compass point' pointing NorthWest will appear. Select this 'compass' and you can bypass the challeneges.

Another secret entrance into the Chamber Challenge:
When you arrive at the chamber go forwards once, then turn right, press UP to highlight a hidden 'forwards' button. This then takes you through another secret passageway arriving directly at Salazar Slytherin's statue. The narrator says, "If only you had a rooster, for its crow is all that is known to be fatal to a basilisk". This will lead you into the Challenge yet again!
