Hint: Exploring new sections:
Use the strafe buttons (LS and RS) when approaching an unexplored section. Strafe into it, then back. This will allow the room to be viewed, and if there is something there, it will not have enough time to react.

Hint: Level with multiple doors:
On the level with all the doors, the door on the right side of the top section takes you to the Exit. The door to the Talisman is in a door in the center of the map. This door is at the bottom of the right side.

Hint: Grave cave:
There are two keys on the Grave Cave level that must be obtained to complete the section. One is at the bottom left section of the map; the other is in the top right portion. Once they are collected, use them to open the bottom door (which leads to the Talisman) and the top door (which leads to the exit).

Hint: Final level:
The last level of the game is not very difficult to complete. The exit is in the bottom left hand portion of the map screen, and the Talisman section is in the area of the top right section of the map.
