I have only one question - I hope it isn't big clue to answer. Is it solvable the way I mentioned it before? Like you get first fat clue, clue A, 100% certain, you get it, you know it is the one and the you get to clue B etc? They are solid, distinct, undeniable?
The answer is YES. From A you can go to B, from B you can go to C and so on. At first, once you have done A, there are no other ways you can follow. But I've been on D for 3 - 4 days now, I went off the road a couple of times, I thought I found something useful like an IP address (a server with something else to solve, like the old puzzle?), maybe a game to play (remember minecraft?) and other stupid things that made me waste time.
CoinArtist told me "The art piece is the final puzzle. Its all you need now" and then I stopped looking for an answer out from this art piece. The answer on how to decode flames, or what to do next, is in the art piece, waiting to be read. For now, this is all I can tell you.
