Hi Goldfinger, saves are not recommended for this game. I think because you can do any area that you want, a save could force you to replay an area you have finished.
Dadguy has been very generous with his time and offers to take the game, complete the puzzle and return it with only this puzzle finished for you. He usually checks each day to assist with this game. Please let's wait for him to help you.
Yesterday is but today's memory, tomorrow is today's dream.
