Really cool game, I love games where I question how it was done behind the scenes. Also maybe consider the amount of single holes not include the count of the double punched holes? So if 1 double hole was needed and 3 single holes, that would show 1 on double and 3 on single. I just thought it was a little more intuitive that way, but when I played the tutorial I figured it out :D great game well done and original.
