This answer goes based off of memory alone and I could be wrong but I believe you can purchase Safe Keys from Victory City. Happy you solved the puzzle! That’s not an easy puzzle!
Gun Shop. Phew! Thanks again. Now I can go back to enjoying this great game.
BTW, as far as the puzzle, using the left control torch to maneuver the right torch onto the square was fairly easy, but to be truthful, maneuvering the left torch via the right torch was more trial and error. Thankfully I lucked out. :)
Edit: I didn't think I was so near the end. The measure of a great game is that you're sorry to see it end, and, indeed I was. Despite the awful grammar and spelling at times, this was truly a great game. Thank you so much for creating and sharing. <3
