Prism: Light the Way review at IGN.

"You know, it's hard to find an original puzzle game nowadays. Puzzle Quest? It's just a gussied up Bejeweled. Puzzle Kombat? Obviously a clone of Super Puzzle Fighter. Snood? Ha, that's clearly Bust-a-Move in an uglier skin. And now we get Prism: Light the Way from Secret Stash Games. The core concept is essentially those "refract the beams of light" challenges in games like Spyro the Dragon or Final Fantasy XII. But hey, at least there hasn't been a stand-alone version of the game for a handheld yet. And it's actually a pretty challenging series of puzzles...just endure the almost condescending set of about two dozen training levels and you're golden."
