FOR THOSE WANTING TO UNLOCK THE GALLERY EASY! go to the "s1d.txt" and others like "s2d.txt". You'll get a code like this in notebook, "496122212", simply leave the first 3 numbers alone, the other after it change all to 0 such as this "496000000", you'll still have to play the stage but all you have to do now is just wait and enjoy! (no offense I love the game, love to have a fullscreen feature too)
