I gonna tell you guys and gals REAL hints!
it's called 1FLAMEN6 because... Wait for it...
16 different flames!!!
yes it is quite obvious there are 16 flames without looking into the title. Your title connection seems to be just a speculation on your side.
16, because there is length, outer color, inner color, and blob, all in two variates.
And I can give out two more secret hints that no one have seen yet but I don't know if the first one is important or not. Let's see who can solve this
The "W hite R abbit" is in the red ribbons
The Phenix and the turtle has "1658" characters
you mean the poem? maybe. I never counted the letters. And thank you for pointing out another rabbit in the picture. We don't exactly know what to do with the first one.
