Temple Adventure Map

This is an adventure style map. you begin with your friend sending you a note that he has begun excavation of a ruin. You yourself are an archaeologist, and you want to aid your friend in the excavation. You set off following a map your friend has given you, however, the small party seems to have dissapeared. you start the excavation alone by fixing the broken door mechanism (Simple Redstone puzzle). The temple itself is very damp, with many odd sounds eminating out of the walls, and darkness everywhere. You head up a staircase and find an old, sealed off room full of cobwebs. Inside there is a rotting chest with many artifacts. You hear a noise and venture out again. the temple seems to stretch into a large chamber with a few rooms. Venturing back downstairs, you investigate the coridoor, however, a heavy stone door slams shut behind you when you step in the room...

Additional Notes

I have no idea what to do next, so i've started constructing a basement area. If you have suggestions, please comment and i will try to implement them.

At the moment, I'm working on a trap in the basement where a door slams shut behind you and the wall at the end of the hall begins to advance. You will have to run to another hallway halfway down to escape suffocation. I've also included Yogscast style notes scattered around the temple and other places.
