Join the March of Progress! A game inspired by the likes of "Canabalt" and "Dino Run", Race 4 Extinction involves running constantly from left to right and avoiding obstacles while collecting items. The player follows the course of human evolution: each level corresponds to a different time period with a new character with unique strengths, weaknesses and abilities.
Me playing through the Cowboy episode :) I set myself the goal of making the game easy enough that I can do a perfect run on each level without too much trouble. Sadly this one isn't a perfect run :S
