Jumping is an expression of joy in humans, we do it because it's fun! Jumping is also very important because it helps us accomplish goals in games:

  • Jumping on enemies and smashing blocks in Super Mario Bros
  • Bouncing around to avoid attacks in Quake (a technique called "bunny-hopping")
  • Leaping across buildings as fast as you can in Canabalt
  • Hopping over deadly traps in the gravity-defying VVVVVV
  • Skipping merrily along the winding roads of Azeroth in World Of Warcraft

To celebrate this gloriously enjoyable method of transportation, we're running a game jam! The first ever game jam hosted by The National Videogame Arcade in Nottingham! It's going to be all about jumping!

We hope to show some of the best entries at The National Videogame Arcade alongside the Jump! exhibition.
