Using the [arrow] keys for movement, negotiate your goo towards food sources and away from anything bigger than you. Slightly bigger enemies will harass you while much larger enemies will swallow you completely.
With precision avoidance games like this, the devil is in the details. In some places Tasty Planet succeeds brilliantly, and in others it falls short. Funny comics between levels provide humor and exposition, but there's only four comics between the eight levels. The bug, picnic and outer space levels are wonderfully detailed in their objects and general design while other levels are just open spaces on grass. Enemy intelligence is generally good, with the leaf-aphid-ladybug dynamic in one level particularly impressive. Bronze, Silver, and Gold medals can be won by time-trial, but the long level length and low enemy spawn rate makes it difficult for the wrong reasons. Regardless, scooping up objects as your googly-eyed goo zips around is satisfying, especially when you go from microscopic to macrocosmic.

Some of Tasty Planet's shortcomings can be forgiven by its preview game nature. Still, even if you're not interested about buying the 50 level iPhone game it's advertising, there's enough content and quality here for the preview to stand on its own legs. Anyone that likes Katamari Damacy or whom longs to envelop the world in their gooey grasp should definitely give it a play.
