Game: Caverns

Caverns is less a video game than it is an interactive piece of art. Created as part of the Ludum Dare 15 competition in less than 10 hours, Caverns let's you manipulate the materials in a small environment to try and grow a variety of different creatures. It's kind of like trying to raise sea monkeys if you were the kind of kid that would poor dirt on things to see how they'd react.
