Achievement Fix
Thanks to a player report, I found an issue with the 69 Moves achievement.
Because of how the move counter works, it wasn't possible to finish a puzzle with exactly 69 moves, making the achievement impossible to unlock.
The achievement has now been removed from the game.
Thanks to TzHaar for catching and reporting this one!
