Thank you a lot for your thoughts!
The answer to that specific question is
, I will adjust that crossword in the next version to make it have only one clear answer for each question.
I will make sure to add a text telling the player they can click on icons to see individual progress.
As for code 6, I just made a stupid typo in the code and the button for code 6 checks the entry field from secret 5. It shouldn't be like that and will be fixed.
The codes for now are only meant to track your progress and basically tell you "you're on the right track". I do plan for them to be more useful in the future.
Again, thank you a lot for pointing all this out to me, it really means a lot!
