Did you update a Jam game after the Jam ended? Joined GMTK Game Jam recently or got a project you're working on? Want to check out other updated games and swap feedback with other devs? This is the "Jam" for you.

The idea is having the same community feel that happens when people are playing each other's games after jams, but for ongoing projects. A time and place for people to share what they're working on.

This is an event hosted by the people of the Post Jam Productions community. Happening once every couple months.

Information

  • This is not a traditional Jam. Submit an updated build, not a new game.
  • Rankings are for feedback on the game. There are no prizes or rewards for winning.
  • Uploads will not be locked at any time. Only reason there is a deadline is so we can setup review swaps.
  • Submissions do not need to be from a jam. You can definitely submit the project you're working on, if you have something and it's a free release.

How to join

  • Work on your updated game anytime before and after the deadline.
  • Submit your updated game before the deadline.
  • Try other participants games and leave feedback. We will be also doing an optional review swap on Discord.

Review swap

  • Trying other participants games and leaving feedback is strongly encouraged.
  • Optional: We will be also doing an organized review swap after the "Jam" ends. Get assigned a couple games to review and get the same amount of reviews you give. Review signups and assignments will be on Discord. You are free to review as many games as you want, not just your assignments.
