Join the jam!

This game jam started 1 day ago, and you still have 2 days left before the jam ends.


  • Preparation Choose a platform that was released before the year 2000, and plan out an idea for a game that's supposed to look and/or feel like it was released on that platform. It helps to analyze other games from that platform for gameplay- and aesthetic ideas. You can form a team if you want to. Also, keep things SFW.
  • Development Once the game jam start has been announced, you're free to start developing your game. From that point on you have 72 hours to finish and submit it. You're free to use third party assets, but the game will be judged only on originally created content. Be sure that you have permission to use any third party assets, and that you credit their authors accordingly! Also be sure to include a text file listing any third party assets used.
  • Submission You must submit your game to the Itch.io game jam-page before the deadline. Make sure that you have either an embedded browser build or a self-contained Windows 10-compatible build that can run without additional dependencies.
  • Judgement The games will all be judged by a panel of retro game designers and vintage gaming persons based on the categories "Quality of Design", "Quality of Aesthetics", "Adherence to Platform" and "Going the Extra Mile" The categories are weighed equally on a scale of "modest", "satisfying" and "outstanding". The decision will be based only on original content, even though third party assets are allowed. Judging can take up to several weeks depending on how many games that have been submitted.
  • Prizes Prizes will be delivered as soon as possible after the jam. Physical goods will take longer for logistical reasons. Our goal is to deliver quickly and as promised, but we reserve the right to make any changes to the prizes at any point, whether before or after the competition, in order to be able to account for unforseen situations.
  • Legal We reserve the right to change any aspect of this jam if necesssary, for instance in order to resolve unforseen issues. The prizes are given out at our own discretion and volition and are not to be seen as payment or compensation for any submitted games. Submissions and submission footage may be used for advertising purposes.
