Spend a weekend making a game using Karl2D and Odin!

What?

  • Karl2D: A library for creating 2D video games that is beginner friendly and easy to modify.
  • Odin: An efficient programming language that focuses on the Joy of Programming.
  • Combined: Have fun while making a game!

When?

  • Start: May 1 20:00 CEST
  • End: May 3 20:00 CEST

How?


Rules

  • The game must use Karl2D in a substantial way.
  • No vibe coding: You must understand and feel ownership of the code.
  • Submit before the end!

Voting

  • When the jam ends, then you can play the other games and vote!
  • Voting ends on May 10 20:00 CEST (1 week after the jam ends).  I will reveal the winner on a live stream on my YouTube channel.
  • Only the submitters can vote. If you are multiple people on a team, then use the submitter as the "vote of the team".
  • To increase your chances of getting voted on, make sure to upload a web build of your game.

Voting criteria:

  • Enjoyment: How fun, interesting, innovative and well designed was the game?
  • Graphics: Did it look nice?
  • Audio & music: Did it sound nice?

Award

The winner gets:

  • A spot on the front page of the Karl2D website: https://karl2d.com/, with links to their game and social media accounts.
  • One hour private video/audio call where we discuss anything gamedev related: Programming, marketing, shipping, production, graphics, sound, etc.

The top 10 games will be featured in a "Karl2D Jam Showreel" video on YouTube.
