The fifteenth yearly edition of the js13kGames competition ended with a record-breaking 317 entries! Last year’s amount was 197 games, and the previous record was 274 games in 2018 - that’s the first time we’ve received more than 300 submissions!
Time to start playing the games to pick the best ones - you have three weeks to do that, between September 14th and October 4th , with the winners being announced on October 5th. If you submitted your entry this year, you can now judge other people’s games and provide them with a vote. This means playing the games, scoring them with the five star rating based on the criteria: Theme , Innovation , Gameplay , Graphics , Audio , and Controls , plus providing written feedback of what you think went well and what could’ve been improved.
The three extra categories are WebXR, Online, and Wavedash - all judged by dedicated experts.
Wavedash with one extra week
The already mentioned Wavedash category is getting an extra week to be submitted to their platform, but keep in mind this should only be about adding Wavedash-specific features or solving any issues you might have with their SDK.
Dynamic listing
Remember that the order of the games throughout the voting period will change. Right now at the top are the ones submitted first to promote sending the entries early. In the next few days the order will change to random , and a few days before the deadline it will switch to showing the ones with the least votes at the top.
Write good feedback
Try to write the feedback in a way you would like to receive it about your own game. Our panel of experts will play your games and provide their feedback too. We have lots of games and a limited list of experts, so that’s not guaranteed, but we’ll try our best to provide each entry with at least one expert comment. Plus, anyone can log into the website and leave their comments though, so feel free to encourage friends and coworkers to join as well.
To cast your vote you need to log in with your GitHub account, visit an entry’s page, play it, and then leave your rating along with the written feedback, the same way as last year.
Editable description via Pull Requests
You might’ve noticed this already, but our forks of your entries on GitHub now have the .website folder containing the game’s zip you submitted, both images, and a README.md file.
That README.md is open for you to be modified with a pull request, so feel free to update it if that’s needed. The formatting also allows you to add links to your written post-mortem, director’s cut version, or a video.
Post-Mortems
While you vote on entries, and the memory of your own game is still fresh, you can write a Post-Mortem: what was good and went well, what you struggled with when building your entry, and what you are proud of - it’s extremely valuable to read the inside stories from past years!
Soundtrack
Don’t forget about João’s initiative to collect your game’s music and turn it into a js13k Soundtrack - the third edition last year gathered 17 different tracks, so I do hope we can beat that this year.
To submit yours please visit the #soundtrack channel in our Slack server to see the details of what exactly needs to be shared with João. You can also contact him directly.
Go vote!
That’s it - thank you so much for participating, and have fun playing and judging the games!
