I randomly got one of the letters from the LET puzzle, but after too many tries, I guess I'm giving up. I also tried to see the source code at your GitHub link ( was going to read the code and find the answers ), but that URL isn't working.
Thanks for the comment! I guess I'll have to work on the hints, cause the game is still pretty hard. Glad you were able to solve at least one puzzle. I can't see what's wrong with the gitHub link rn, but I'll also work on fixing that when I can.
