Game Off 2019 theme announcement

Game Off  is our annual month-long game jam (hackathon for building games). This year’s theme is LEAPS AND BOUNDS.

You’re welcome to interpret the theme however you wish, but if you need some ideas to kickstart your creativity, maybe your game could:

  • Make your character evolve to overcome challenges
  • Add obstacles to test your hero’s ability to leap into action
  • Deduct points for anything going out of bounds
  • Duck, dip, dive, and dodge an enemy that’s changing or moving rapidly
  • Take place in the year 2020, the next leap year

Maybe the year 2020 will lead you to think about hindsight being 20/20, and that’ll inspire even more ideas around time travel, decision-making, or something else. Let your imagination run wild and create a game loosely-based or inspired by that theme using whatever game engines, libraries or languages you prefer before December 1st, 13:37 PT. Work alone or as a team. Most importantly, have fun!

The community feature is enabled for this jam—it’s a great place to share tips, ask Game Off and game development questions, and more.
