E.V.O.: Search for Eden the tedious gameplay and subpar graphics. "E.V.O.: Search for Eden" is a side-scrolling platformer action game where players must navigate a creature of their own design across a number of environments resembling Earth's past. The game is divided into five distinct geological periods: the Cambrian Period and the Ordovician Period of the Paleozoic Era ("The World Before Land") from 500 million years ago to 450 million years ago, then the Carboniferous period ("Early Creatures of Land"), the Mesozoic Era ("Age of Dinosaurs"), the late Neogene period ("Ice Age"), and finally the early Quaternary period ("Early Man"). Each period has its
South Polar region of the Cretaceous temperatures caused by the high amounts of carbon dioxide and possibly methane greenhouse gases in the atmosphere. This caused a lack of permanent ice coverage in the polar regions, though the carbon dioxide level dropped between 115 and 66 million years ago (mya), possibly allowing some permanent ice cover. It is possible that, throughout the Cretaceous, several small ice sheets developed. Increased tectonic activity, causing more geothermal heat, may have prevented glaciation and increased global temperatures. Temperatures may have been up to 15 °C (27 °F) warmer than they are in the modern age. The landscape of the Middle Jurassic
