The balancing act here is just so so clever, where, if the player fails, it is entirely his own fault, and is in almost no way the structured design of the game (except for maybe the way the Zs zigzag). That is really something cool, and I can't really think of any other game off the top of my head that pulls it off just as elegantly as this.
I'm glad you were able to see the message hidden within this game
