Tasty Planet: Back for Seconds

Control a tiny ball of grey goo with the ability to eat anything smaller than itself. The more it eats, the bigger it gets! Soon you'll be able to eat the entire planet!

The story begins with the goo eating a time machine, causing him to be sent back in time. Playing as the goo, you'll eat your way through six different time periods: modern, Late Cretaceous (i.e. dinosaurs), Ancient Egypt, Ancient Rome, Feudal Japan, and the distant future.
