Great to hear, and congrats on making it to 10! You are correct, the initial row can have multiple solutions, the idea is to use mastermind/wordle logic to deduce, once you do so it reveals the next row which provides more clarity on the coloring and so on!
One limitation I had due to the hardware was in the puzzle generation, when I initially built this in bash the generation checked to ensure there was only 1 possible solution for the full puzzle, this is tooooo compute intensive for the GB hardware and meant the puzzles would generate slowly and sometimes error out.
Thank you for the feedback on the story as well, I want it to be narrative but totally see some potential value in artwork instead of the plain text!
I hope the learning curve keeps you engaged, I am really proud of the ending. It ties the whole narrative together!
