Thank you for the feedback and for taking the time to play the game!
I totally agree that there should be some kind of punishment, that is definitely on the list of features I want to include if I ever revisit and improve the game.
To be completely honest, I just ran out of steam to include that :D Plus, it was kind of fun seeing friends and colleagues I’ve shared the game with go from carefully filling out the lines to making a total mess in order to score as many points as possible. Haha!
Thanks again for your feedback, I wish you a happy holiday season!
