First level a 2 year old could finish. The second level wasn't hard and had one hole that needed to watch an ad to open. Great, didn't need it, but it was there. 3rd level I barely got started when an ad popped up mid move so there was a very good chance you would accidentally click on it. This is another ad-bait game that ruins gameplay with a constant bombardment of ads at dubious placements most likely to catch a player off guard.

Re-skin of the game screw master with less levels. I think that it's the same developer too. Game isn't bad, but I'm docking stars for the advertisement for this game. I don't like the reverse psychology that are so frequent these days. If you want me to play a game, show me what's good about it. Don't show me a brain dead machine failing it followed by acts of violence. That is not appealing and I won't keep this game. This was an accidental download and I won't be keeping it.

Too easy, too many ads, and not very stable. Crashes for no reason. Impossible to complete "hard" levels - you'd be done with it, and the clock just stops and doesn't let you out of the level. Uninstalled.
