Winners

Community Choice: Di-Miner by Catelyn

Judges Choice: You Do Doodle Too by Loten

Schedule

Jam: July 9 to 19 (1pm ET)

Community Choice voting: July 19 to 26 (1pm ET)

Winners and ratings announced: August 2 (1pm ET)

Limitation (Required)

Create a game controlled only by mouse input. For the purposes of this jam, this means mouse position, three buttons, and scroll up/down. (We're aware that a mouse can have dozens of buttons, but this is our definition for the limitation.)

This means no keyboard interaction (other than what the operating system enforces) and no gamepad support (even if it simulates using a mouse).

Theme (Semi-Optional): ANOTHER WORLD

The theme is meant to be an inspiration to kickstart your game ideas. You are free to interpret it however you like.

The theme is also optional, but one of the five rating categories is Theme/Limitation, so it counts for about 10% of your score.

Challenges/Diversifiers (Optional)

Looking for additional challenge in the jam? You can use any number of diversifiers listed here.

Judging and Prizes

When the jam ends, games will be open to rating by anyone who submitted a game. The highest scoring overall game will be crowned Community Choice. Check out the Ratings Guide for how to interpret the categories.

A panel of judges will also rate games based on a rubric to determine a Judges Choice winner.

Community Choice voting will take place in the week after the jam ends. Winners will be announced and ratings released one week after voting ends to allow extra time for judges.

All winners will receive:

• The jam-winner role on the 8 Bits to Infinity Discord server
• A place in our list of jam winners
• An additional secret prize
