You could start by running into the Room of the Three Gargoyles. Push in the right tongue, and a door might lead you down a staircase into the Wall Climb. Here you must choose your next path. You could race up to the Observatory spin the sundial, and pass into the Room of the Golden Idols. Once there, push down on their bases to release the doors. That may take you below or lead you into the Shrine of the Silver Monkey. Assemble the statue there, and you may be headed for the Torch Room. If the elevator is up, you could jump in the elevator and descend into the Mine Shaft. Next, you could climb up the ladder or plow through the stone wall. Find the key, and it may unlock the Tombs of the Ancient Kings, allowing you to enter the Swamp. If you escape, you might have a chance to sit upon the Throne of the Pretender. If the correct door is unlocked, you could crawl through the Pit of Despair and, finally, make your way through the Cave of Sighs and back into the Temple Gates.
The choices are yours and yours alone. Good luck.
