Of Light and Darkness (PC)
Tips: Keep a piece of paper next to you and keep quick notes as you play. With each flash of starlight, run immediately to the apocalyptic devices and collect the new artifacts--then write down the color of star that flashed and which artifacts appeared, so you'll know later on what orb combination will redeem them all. There are some rooms which can only be accessed by teleporter pyramid. The lust room on level one is one of them. Figuring out which pyramid takes you there, and keeping track of it, is the key to completing that level. Don't forget that you can flash an apparition with white light to make it go away. If a soul has beat you to the A.D. and finds its totem before you, a white flash is the only way to clear the machine--you'll lose both the apparition and the artifact that way, but you'll get a second chance at the artifact.
