For starters, I really like the game. Because of that I would like to do some suggestions. Like Xoros mentioned the valididation of the no mistake star should be done when you have moved all the tiles. To compensate this loss in difficulty you can add a star for when you don't use the notepad. Could you also add a mute button for the sound or a menu so you can adjust settings without quiting the levels.
I think you need to have 500 sextillion diamonds, because it has no currency.. I have the same problem, but i am only 8 blocks away to clear the map for the first time :D
Ardelo: next to the webaddress in firefox there is a button with depicting a brick. If you click it you can change the settings for plugins, because firefox initialy blocks it
