encountered a glitch - if you earn a key/statue, and quit before placing it (or if your browser crashes), you have to start a whole new game, because you restart without it and recompleting the level doesn't re-earn the key.
toxicvoid: for level 29, first click the four large blue circles on the outside bottoms of the pyramids, so that the greens are on the bottom. Next, click the bottom middle small blue circles of each pyramid to expose them to the big blue rectangles. Finally, send first the vertical, then the horizontal rectangles crashing through.
