Near the end of the game, you are in a tomb with infinite doors. You have to find the correct series of doors to progress. Go to the landscape view. Always start at the door with the face above it and go clockwise. The order is

1. Fourth door from the entrance
After you have successfully done this you will be taken to the second level of this room. It is almost the same, just with more doors. The order is
1. Fourth door from the entrance
An intermission sequence will then follow.
In the circular room you find in the tomb, there are doors that you must enter in the correct order, or be teleported back to the start. One way to make sure you go through the correct door is to listen carefully. When you are in front of the next door that you need to enter, you will hear the sound of trickling water. This indicates that you are standing in front of the correct door. Repeat this until you have solved the maze.
When you are almost at the end of the game, you will be trapped in a room with a lot of doors. Every time you go in one, you end up back where you started. An easy way to find the correct doors is to run by the doors until you hear a splash of water. As soon as you do, stop and go into the door. Repeat this three more times and you will be at the second set of doors. Do the same thing four times and you will pass the level.
