I found the Light reflecting part in Myst3 Exile EASY, maybe because of this Free Mirror game, Give it a try see how many of the 50 levels you can complete
A free game of laser beams and mirrors, for the Windows PC and Mac OS X. Features 50 levels of fun! No cost, no ads, no popups, just a game that will absorb as much time as you're willing to spend on it.
BEWARE: This game is addictive as hell. It's a great puzzle game - simple to get started with, and wonderfully challenging after the first few easy levels.
Have a Great Quest,
He can do more for Others, Who has done most with Himself.
