this will start with it asking you if you want all the puzzles, only the five by fives, only ten by tens or only 15 by 15s! then in a random order, from all the puzzles unlocked, you will be given puzzles. I think this is necessay because after you unlock them all then the only way to replay them is by choosing them by their title which seems to provide an unfair advantage.
Another great idea. We’ll look at this if sales pick up.
