Summary: Though the game itself is a great puzzle, it lacks rewards and a plot to engage the player. It requires that you save x many goo balls, but suggests that you save more. While this does present a new challenge, getting away with the minimum gives the same feeling of achievement as only using two goo...
Summary: The mission is simple: you have funny looking goo droplets that can make structures out of triangles. You have to get the structure from point A to point B using some of your droplets. The game is challenging, but surprisingly not frustrating.
Summary: This game appears to be very simple with the same goal in mind for each level--to get all the goo balls up into the pipe. But it is also very challenging because with each level you have to figure out how you are going to build up the goo balls to reach the pipe.
Summary: I really enjoyed this game, as did my husband. The challenges start off quite simple and grow more difficult at a steady pace but they are never impossible. Some of them just take a few (okay one took me about 10) restarts to figure out your strategy.
