Prism: Light the Way review at Gamer's Temple.

"Prism: Light the Way would more appropriately subtitled "Light Them Up". That's because your goal is to provide life-sustaining light to creatures called glowbos who've made the unfortunate and tragic decision to live in a cave. Rescue comes in the form of bulboids, creatures that shoot a strong and steady beam of light out of the top of their heads. Unfortunately they can only shoot that beam in one direction. Your job is to use mirrors, crystals, and beam-splitters to direct the light to the glowbos before they die."
