From Dingo Games:
Control a tiny ball of grey goo which eats everything around it. The more it eats, the bigger it gets. The goo eats anything that gets in its way: dirt, bacteria, bugs, fish, mice, cats, dogs, cars, trees, houses, and more. Soon the entire planet will be eaten by this crazy ball of goo. Fortunately you're on the goo side. Version 1.0.3 may include unspecified updates, enhancements, or bug fixes.
