I looked on the game page of this game and also viewed the video and am going to try it out. However, what I wanted to point out is that the game page (where the picture of the game is displayed above "free for 1 hour" clearly says there are 18 levels, and it ALSO says that you can use your own pictures to create puzzles....so I would think you could create as many as you wanted, though you might not be able to keep them all in the game at the same time.
I'm sorry the OP was disappointed, but I think maybe this person didn't notice these things.
