Tasty Planet

Tasty Planet is a 2006 video game similar to the Katamari Damacy line, but with Grey Goo instead of the Katamari ball. You begin as a micrometer-sized bit of experimental Grey Goo bathroom cleaner, eating tiny dust particles, but get free, and continue consuming, growing to eat mice, people, buildings, asteroids, the Earth, stars, a black hole, the entire universe, and finally SPACE AND TIME ITSELF Though it pretty much Tastes Like Diabetes.

Made by Dingo Games.

In 2010, the sequel Tasty Planet: Back for Seconds has come out, in which our protagonist can time travel. It also features multipart levels, which means once you reach a certain size, the game zooms out to reveal a bigger scene, and you find yourself small again with new things to eat.

 * All the Worlds Are a Stage: In Back for Seconds, the last level in each time period is a concatenation of multiple levels from that period, with an added twist ending.
 * Apocalypse How -- Class 0, then stepping from Class X through X-4.
 * Blob Monster
 * Brain In a Jar: The Professor and assistant become these to survive until the blob appears in the future.
 * Cute Machines -- It's a blob with cutesy eyes!
 * Earthshattering Kaboom
 * Everything Trying to Kill You: In the ocean and cosmos, almost everything bigger than you will kill you.
 * Extreme Omnivore -- Technically Ultimate Omnivore.
 * Genre Blind: The scientists who created the blob have evidently never heard of the Grey Goo scenario.
 * Gone Horribly Right
 * Grey Goo
 * Made of Explodium: In the sky levels, planes will explode on contact with other planes, hot air balloons, the grey goo, kites, or even birds.
 * Marathon Level
 * Mega Microbes: That eat galactic superclusters.
 * Nanomachines
 * Non-Malicious Monster: The grey goo.
 * Our Time Travel Is Different: Lampshaded by the scientists.
 * Planet Eater
 * Reset Button: Back for Seconds starts off with the same scientists inventing the same Grey Goo, but this time it's just something the elderly scientist made out of boredom.
 * Sci-Fi Writers Have No Sense of Scale: The goo is supposed to be able to eat anything smaller than itself, but sometimes what it can eat makes little sense. For example, it can eat entire sharks when it's less than a meter in diameter.
 * Serial Escalation
 * Time Travel: Back for Seconds has the Grey Goo eating a time machine, then going back to the Late Cretaceous, then to Ancient Egypt, Ancient Greece, feudal Japan, and the distant future.
 * Unrealistic Black Hole: In Cosmos 4, black holes actually suck in stars (yet for some reason don't suck in the grey goo...).
 * Villain Protagonist: Arguably, the grey goo.
 * Womb Level: During the tutorial levels of the first game, the grey goo bites one of the scientists and spends a level in his bloodstream.
