I'm glad you enjoyed the game! I'm impressed that you managed to complete it without solving all the puzzles in your first playthrough!
As for the puzzle you're stuck on, perhaps counting characters in the username would help
Thanks, although I only had to fill in a few blanks and I happened to see what answer it could be.
I have counted the characters as the final hint suggested and tried to do all kinds of things with them. Used the alphabet cypher tool, viginere, caesar, summed it all and tried to enter that, returned to a puzzle related to the sum but nothing seems to spit out anything of use. Am I misinterpreting the hints?
