Have you ever played a runner game online? I might you have, there are many, floppy bird is one example. Mario run is another. But did you know the original run game that started this entire popular genre? It had to be the Run 3, a game about a little alien critter that runs through outer space on a gravity-shifting tunnel where the goal is to not fall down. This classic game was made using Flash, like many other games. Run 3 is actually the third installment with many improvement from the previous. If you like Run 3 you will also like Slope Game, which is gaming popularity recently where you roll a ball on a platform without edges and try to not fall off.
