It's official: the results for the 11th Alakajam! are out! You can find the results below.

Solo winners | Team winners | Unranked games

A huge THANK YOU to all of you who took the time to recreate their game page, and most of all to replay ratings (sometimes even comments) on the games you played. Thanks to our collective efforts, pretty much every ranked game having its page restored has managed to get ratings! The past few days have been a bit strange, but in the end the event could be completed normally which is the best outcome we could expect.

Well, other than, say, servers not burning to ashes :,-)

Final words on the lost data

If, for some reason, you've been away from Alakajam for the past 10 days and can't find your game/user account anymore, please check this page for context. Game submissions will remain open for the unranked division for a while, in case any of the users behind the dozen of games that weren't recovered decide to recreate their game page.

I hope to eventually make a postmortem of the past events as a blog post, with some advice to everyone on how to set up reliable backups that prevent the scenario we got.

Upcoming events

• The 12th Alakajam! will take place on the 25-27 June 2021 week-end!
• Before that, a new Kajam should be held as a less competitive, more relaxed event to practice gamedev. Details have yet to be announced.

Thanks for being part of the 11h Alakajam, we hope you had a nice time, and look forward to the 12th! See you soon <3

11th Alakajam data wipe

In case you missed it on Wednesday, the Alakajam server has been involved in an actual fire, impacting a lot of servers from French company OVH. The company has confirmed to us today that the server will not be recoverable. The version of the website you are currently browsing has been restored from a backup dating back to February 20th. That is, one week before the jam.

⚠️ ⚠️ ⚠️
If you created your Alakajam user account after February 20th, your whole account, game submission, ratings and blog posts are unfortunately lost(*). If your account has been created before that date, some data (game submission, posts, comments) may have been already restored.
⚠️ ⚠️ ⚠️

We're sorry about the troubles, and wish we anticipated this kind of disaster scenario better. At least know that the new server is already subject to a weekly offsite backup… Of course, everyone can still get back on board :)

(*) All blog posts are available in the Google Cache, as well as a majority of game pages. You can access a handy archive dumping all found pages here.

Bonus round for submissions & ratings

As an entrant to the 11th Alakajam, you are invited to:

• Recreate your user account if needed ;
• Resubmit your game (unless you still see it in your account, which means we could recover it from the Google cache - except some details like high score settings) ;
• Re-cast the ratings of the games you have already played ;
• And of course continue rating more games and exchanging feedback at will, until the end of the ratings phase.

To give everyone a better chance to get ratings again, and a ranking at the end of the jam, we have made the following changes:

• The end of the ratings phase has been extended to Sunday March 21st ;
• Game submissions will remain open until then ;
• The minimum number of ratings has been lowered a bit ;
• Casting ratings has been open to everyone, not only jam entrants.

Happy playing!

On March 10th, at around 1am a fire started at a site of our hosting provider, which includes Alakajam's server. While we wait for the hosting company to resolve the issue (which is planned to take up to next Monday), we have set up this Alakajam install, from our last backup, on a completely new machine.

On top of this incident, we have made the mistake of not setting up automatic off-site backups for Alakajam. As you can see from the game submissions being missing from the site, our last backup was made before the 11th Alakajam week-end. We don't know for sure whether data has been lost in the fire or not, so in the meantime we chose to freeze the website.

Note: in the picture, Alakajam is somewhere in the small building on the right of the burning one. As it turns out, virtual servers are… not that virtual. (14/03 EDIT: In the end we turned out to be in the fully burnt building)

About 11th Alakajam's rating phase

Here's our current plans for next week:

• Plan A: We recover the game submissions & ratings. If so we'll restore the up-to-date version of the site, everything goes back to normal, and we'll give an additional week to end the ratings phase normally.
• Plan B: If data really is lost, we'll reopen BOTH entry submissions and ratings, for long enough to let everyone jump back aboard and re-cast ratings to the games they played.

Thanks for your understanding. Let this be a lesson for us all to never underestimate backups!

How ratings work

For the next two weeks, all entrants are able to give ratings on other games. Take some time to play & rate games, and even better, write some feedback about it! Constructive feedback is one of the best ways to learn and improve one's game design skills, so please dish it out in buckets. While people who didn't enter the event cannot rate games, they can still post reviews.

By rating & commenting (even on Unranked entries), you will gain Karma that makes your game more visible to others. A high Karma gives you more chances to get ratings yourself and reach the minimum of 10 to be classified. Otherwise, you will not get a final ranking!

Ancient Mushroom Award

Original announcement here

The ANCIENT MUSHROOM AWARD can be given by anyone, to anyone during the ratings phase. When you see a game that makes worthy use of MUSHROOMS, simply paste the badge picture into a comment for the award to be counted. At the end of the jam, we'll tally the amount of given awards… and nominate the ANCIENT MUSHROOM KINGS :D

Code to copy:

End of ratings

On March 14th, at 7pm UTC the final results will be released and the winners crowned :)

Go go go! Play and rate games!

A faction of gamedevs has decided to show their passion for the Mushrooms theme, and integrate it into their games anyway. So let's give everyone an additional (an totally optional) incentive to put mushrooms in here some way or another!

The ANCIENT MUSHROOM AWARD can be given by anyone, to anyone during the ratings phase. When you see a game that deserves it, simply paste the badge picture into a comment for the award to be counted.

At the end of the jam, we'll tally the amount of given awards… and nominate the ANCIENT MUSHROOM KINGS :D

Award giving kit

• Badge markup for giving the award

Looking forward to see your games! Don't forget to take breaks and have a decent night of sleep :)

With the theme now revealed, the 11th Alakajam! has started! Good luck to all!

Big thanks to @DanaePlays and @Aurel300 for hosting the awesome launch stream! If you missed it, you can still watch the replay on her Twitch channel. If you like The Elder Scrolls, you will also enjoy Danae's regular streams, where she usually goes exploring the huge world of Morrowind.

Submission times

The end of the jam is depending on whether you pick ranked or unranked. You can create your game page at any time during the jam (and update it any time after it's created):

• Ranked: February 28th 7:00pm UTC, which means you have 48 hours (+1 hour for late entries to create their page).
• Unranked: March 1st 10:00pm UTC, which means you have a bit more than 72 hours

Cool things to do during the jam

• Stream your development process. Join the event as a streamer from your dashboard to let everyone know about it, and possibly get featured on the front page during the week-end! This will also have the side effect to let you enter the streamer competition.
• Write a blog post: Share your thoughts on the theme, post your progress, images of food or gifs of cute animals. You can also free to use posts for advertising live jam streams.
• Come relax on the Discord server, tweet about #alakajam and/or follow the alakajam Twitter account.
• Initialize your game page early!

Everyone have a nice week-end, and see you on the other side ;)

My first attempt at a raycaster is made in Rust and finally getting some progress. I'm basically following the Lodev tutorial while making the code a bit more object-oriented.

The first fancy thing I've done is making the game map load from a PNG file, with each pixel matching with a tile. Even the color palette is dynamically loaded (from another PNG holding a single row of pixels), and can be easily changed. Indexes in the palette hold the semantics of each tile:

• Index 0 is a floor
• Index Len - 1 is the player spawn
• Index Len - 2 is the initial tile the player is looking at
• Other indexes are walls of various colors

The 2020 edition of Feedback Fortnight will be from November 22 to December 17! This is an event where you submit any game project, complete or not, and ask for feedback. If you enter the event, you are also invited to give feedback to the other people, as the goal is indeed to exchange feedback between participants. To make this more effective, we have a "karma" system in place so that the more feedback you give, the more visible your game is.

What can I submit?

This is a very open event, where you can enter for instance:

• A personal hobby project you have been working on this year
• A game jam entry that didn't get enough feedback or that you expanded upon since
• A work-in-progress commercial game project (as long as you keep your build free and publicly available)

Of course this can be either a solo project or a team-based one.

Event schedule

• Preparation phase: on November 22, the event will open submissions.
• Feedback phase: on November 29, all entrants will be formally invited to start playing and reviewing each other's entries. In the meantime, submissions will remain open until the last few days for late entrants.
• End: on December 17 the event will be officially closed. The games won't get any rankings or ratings, just feedback. No bragging about being first, but who cares, you will get good commentary!

Tips

• To improve the quality of your feedback, give indications on what aspects of your game you are most looking for feedback on. This is especially true of bigger projects like commercial games.
• If possible, make your game build available on multiple platforms or the web
• Don't neglect commenting on other games: longer, more constructive comments get rewarded more "karma", and this karma score helps you get displayed higher in the game list.

See you then!

The next edition of the Alakajam! series starts on February 26th!

As always, the event is about making a game, from nothing, in a weekend. Teams or solo devs, beginners and professionals are all welcome to participate. If you opt-in to the competition, you will be ranked against every other contestant! If you prefer a more relaxed setting, the unranked jam will still give you an opportunity to get plays and comments.

Schedule

Dates	Phase	Description
February 12, 7pm UTC	Theme submission and voting	You can submit theme ideas for the jam and vote for all other submissions.
February 19, 7pm UTC	Theme shortlist	Only the best 10 themes are kept. Rank them by order of preference in this final phase of theme voting.
February 26, 6pm UTC	Countdown stream	An official stream is held on Twitch to launch the event!
February 26, 7pm UTC	THE JAM!!!	Start making a game solo or as a team, and simply submit it before the deadline!
February 28, 7pm UTC	End of ranked jam	The main competition ends here, exactly 48 hours after the start time. Submissions will remain open for an additional hour after the deadline.
March 1st,10pm UTC	End of unranked jam	If you want to go for a relaxed weekend - or need more time - you can create a game in the 72 hours of the unranked jam.
March 14, 7pm UTC	Results	After two weeks during which all entrants are invited to play, rate and comment on other peoples games… The results are released and the winners crowned!

Rules

There are three divisions:

- Solo, in which you make a whole game alone in 48 hours
- Team, in which any number of persons can gather to make a game in 48 hours
- Unranked, a more open division which grants about 72 hours to finish the game. Useful for those not interested in the competitive aspect of the event, want to work on an existing project of theirs, or simply did not finish their game in time.

See the full rules for the Alakajam.

How to enter

All you need to do is:

1. Create an account on this website
2. Publish your game before the deadline

A lot of participants also post an "I am in" blog post presenting themselves or their team before the event. Describe what tools and frameworks and engines you will use to create your awesome game! Which themes do you like? Let us and the community know!

If you can, feel free to spread the word about the jam - the more we are, the merrier! glhf ;)
