Lovely Planet by developer QUICKTEQUILA (published by tinyBuild) is a fantastic and surreal first-person shooter/platformer made with speedrunning in mind. Players will race through 100 levels with building complexity trying to shoot all the enemies and reach the goal in record time. I highly recommend Lovely Planet and hope this will take off in a big way for fans of speed running! Check out the game on Steam at the link below.
