Be careful, and don't fall off the edge!!
*joke mode off*
Here is my new level, pretty average IMO, but includes my newest visual magical idea (btw, I still think that I've done a lousy job on it, as you can see the *thing* happening, however, I simply couldn't think of anything)
Watch the boulders fall off the edge of the level and then disappear!

At the end, as soon as you see the sign, stop pushing the box and take a few steps back to avoid Mr. Kablooey.
