Japanese Tile Puzzle Bypass: Click several times in the upper right corner of the screen. That is, not the puzzle itself, but the full game screen. Then, put two or three tiles into the puzzle picture, anywhere. The puzzle will solve itself, and you should find something in a niche behind it.

There is one cheat built into the game, though--if you find yourself frustrated with the black and white grid puzzle (otherwise known as the "nonogram," "Conceptis," or "Japanese tile puzzle,") you can give yourself a hint or even opt out of it completely by clicking in the upper right-hand corner. This causes a large section of the puzzle to be automatically filled in for you. Do it enough times in a row, and eventually only one tile will be left for you to put into place yourself.
