We're making games like the elders before us:

  • no engines
  • no vibe coding
  • all you

You can use game libraries and any tool to help speed you up, create fun tools as well, but cheating - it's just you and your IDE

  • You can go solo or in a team of up to 4 people
  • You can submit multiple times, the more games being made the happier we are :-D
  • Aside from a name, ensure your entries got instructions on how to play. 
  • If you're using pre-made assets make sure you have permission to use them!
    • Check the license and copyright
    • Give credit if needed. If not needed, consider giving credit because it's a nice thing to do
  • No new submissions or updates are allowed when the judging period has started.  We'll make an exception if the update fixes game breaking bugs. Notify admins first before updating.

Judging Criteria

Games will be ranked with these criteria:

  • Technical Excellence/Wizardry
    • How impressive was this to code? Use the game, as well as any developer anecdotes about how it was made!
  • Gameplay (Quality and Fun)
  • Art, Audio & Polish
  • Theme & Originality

Note: you will be required to share you source code as well

What can I use to build it?

Game engines like Unity, Godot, Unreal are not allowed. Yes, that includes GameMaker, Defold and all the other ones not listed as well. If it calls itself a game engine, and gives you a suite of integrated tools to make a game, you can't use it.

Find yourself a programming SDK, an IDE, and make a game.

You must target at least Windows or HTML5 in your exports! Those are the most common platforms to play games, but support as much as you can!
