@Beau Skunky That is likely the case yes, I'm not sure I recall any "Light themed" puzzles or anything existing outside of the Spirit temple though, but then I suppose some of those could have been pulled and re-used in said Spirit Temple, a lot of things in the spirit temple were based on reflecting lights, as well as the Mirror shield, I wonder how much of that could have been from the Light Temple originally?
Then again it's been years since I played OOT last, and even then I think I quit a few dungeons in, so I'm probably forgetting many things relating to what was in Ganons Tower :P
