This is a great game and I laughed many times as rocks were dropped on my head as you'll see in my Gameplay:

John D. Moore, thank you for this fun game!  I love the sound effect when the rock hits the cage.  I didn't expect to play this for so long, but that level at the end of the second map was too intriguing.  Great job and I may venture out into the rest of the series after I finish this one.
