In each level you have little Goo Balls that can be drawn by drawing in a combination with other Goo Balls, makes it possible to build bridges and towers. The aim of each level is a kind of big vacuum cleaner to errechen and still plenty of Goo Balls over to have to be sucked from the vacuum cleaner.
Later in the game turned out differently färbige Goo balls have different properties, some are reusable helium balloons are others which can hold strings of goo balls in height, etc.
All in all the game is well done, it tells a universal albeit a bit crazy story of Goo World. Unfortunately, as with all good, the game was after some time through the game, I would have liked more level since it was not for a long time was too bland. 5 of 5 earned points!
