Developers Chris Figueroa and Ryan Schaefer hit Kongregate this week with Train-Cognition, a Unity-based browser game developed for the 48-hour Indie Speed Run competition.

Train-Cognition is a short "Wild West Platforming Shooter" in which players fend off attackers aboard a speeding train using a simple mouse-and-keyboard setup. There's a twist to it, and you can't help but love the way you can shoot off your enemies' hats. I'd love to see the concept expanded in a lengthier game.
