Super Addictive

Very fun game, difficult to put down, and despite its simple premise is able to stay interesting for extended periods thanks to repeated universe recreations, Mars, and Pluto. New types of upgrades and cows when the universe is recreated would be nice, though, as well as changes to Mars and Pluto rather than just Earth.
