Too bad the creator of this game compensates his lack of creativity with such primitive methods as forcing players to complete the whole last section in one sitting.
I recommend making harder, more challenging levels instead of resorting to such lame tools.
One click on the wrong button can ruin a lot of (repetitive) work. You are just further wasting our time with an "okayish" game.
