Yo! I rather like your AVN but found that the use of puzzles was very frustrating.
Personally I find puzzles annoying and frustrating, Im terrible at them. So when you place a puzzle as a stopping point to the rest of the AVN I just get stuck, unable to continue the story.
Which of course leads to me just quitting the AVN.
Please consider making all puzzles skippable or at least putting in a limit to how many times it can be failed or how long it takes before a game over occurs.
I can accept a Game Over if I deserve it but will just be frustrated and annoyed if I cant proceed at all...
