I am utterly addicted to this game even though Im sure it will give me a nightmare or two; and Im positive it will give my friends them as they could only play until level 3 without being too afraid even though they loved it. Not overly difficult in later levels so that you want to quit playing like some games, as Im on level 33 (started last night) and havent had to redo a level more than thrice.
Only problem was sometimes Id swipe to throw a rock and it would move me forward and get me killed instead.
Hit a home run on this one.
