Working renderer and movement 5

Wan • 2 years ago on 9th Kajam entry  Ancient Digipts

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

What did you work on this year? Let's exchange feedback! 0

Wan • 2 years ago on Feedback Fortnight 2020 

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!


  • 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!

Schedule of the 11th Alakajam! 0

Wan • 2 years ago on 11th Alakajam! 

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.


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!


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 ;)

The Jellymancer special event: a recap 0

Wan • 2 years ago on 10th Alakajam! 

The Jamician, mascot and protector of our community, has recently challenged his evil twin known as the Jellymancer… And lost ownership of Alakajam! in the process. After some drama, this has just been confirmed by the Jamician themselves, concluding the controversy about the challenge results. In case you missed the events that led up to it, here is what was previously on Alakajam!

A disturbance in the jam

The 10th Alakajam! has been host to unusual announcements, starting with a mysterious tweet several weeks before the jam. When theme submissions started, surprise changes where made from the usual rules, with the theme submission limit raised to 10, in the name of "chaos". It became clear that Alakajam! had been broken into by a mysterious character.

The second phase of the theme selection saw 20 themes shortlisted instead of 10, with the list itself getting shortened one theme at a time as the jam got closer. The Jellymancer then decided the jam would have not one, but three available themes:

The Jamician's Challenge

During @DanaePlays and @Aurel300's jam launch stream, The Jamician took a chance at getting rid of his opponent, by challenging him to a gaming tournament. In the competition, three games from the jam would be played by everyone for a few days. The Jellymancer would compete in it, and commit to leave the community alone in case of a defeat… while victory would make him the owner of the jam.

When the tournament took place, the Jellymancer only posted modest scores and it seemed clear that the players had managed to beat him fair and square. But in the last moments of the competition — in an evil twist fitting of the Jellymancer — he posted much more skillful scores, including a controversial top spot at the Square Maps game.

His surprise victory triggered a lengthy investigation… Before The Jamician finally had to accept the victory of his opponent.

And this is how Alakajam! came to be… in the hands of C H A O S

The Jellymancer has now taken over Alakajam 0

Wan • 2 years ago on 10th Alakajam! 

Who would have guessed? It seems like the Jellymancer has outsmarted us, posting incredible high scores at the last minute to take over the top spot of the leaderboard! I do not know what this means for the future of Alakajam, but our new master has already started updating the website to match their taste.

While we wait to discover his next move, I'd still like to congratulate everyone who took part in the tournament and the event in general. We hope you had fun with this special 10th Alakajam :) Speaking of which, unless our new master decides otherwise, here's the dates for the next one:

The 11th Alakajam will be held on 26-28 February

Let the best player win! 0

Wan • 2 years ago on 10th Alakajam! 

The tournament of the 10th Alakajam has now started! From Thursday (October 8, 7pm UTC) to Sunday (October 11, 7pm UTC), everyone gets to compete on a selection of three games made during the jam. The competition is open to everyone having an Alakajam account, it is not restricted to the jam entrants.

Try you best to beat the high scores of your opponents… and in particular those of the Jellymancer, who is playing to possibly take over the entire Alakajam community from the hands of the Jamician (see video below in case you missed the launch stream).

Jam results are out, tournament starts soon! 0

Wan • 2 years ago on 10th Alakajam! 

After two weeks of playing, reviewing and rating games, the results of the jam are finally out! Congratulations to the winners… and of course to all of you who took the time to play and post comments on the jam entries: getting people to actually play and review our creations is possibly the best part of game jams :)

High score tournement

Speaking of tournament, we still have to deal with the Jellymancer, who has been challenged by the Jamician to a tournament (see video below in case you missed the launch stream).

The tournament will be held from Thursday (October 8, 7pm UTC) to Sunday (October 11, 7pm UTC), and will require you to beat the Jellymancer on his selection of games. The chosen games will only be revealed at launch! Depending on the specifics we may contact their author before the start, for instance to tweak their entry page or reset the game scores, in case there is a post-jam version of the game we can use over the 48h one.

See you then!

The game ratings phase is on 4

Wan • 3 years ago on 10th Alakajam! 

For the next two weeks, all entrants are be able to give ratings on other games. Take some time to play & rate games, and even better write some feedback about it! Getting 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 will make your game more visible to others. A high Karma gives you more chances to get ratings yourself and reach the minimum of 8 to be classified. Otherwise, you will not get a final ranking!

On October 4th, at 7pm UTC the final results will be released and the winners crowned :)

Go go go! Play and rate games!

First mockups 1

Wan • 3 years ago on 10th Alakajam! entry  Gimbal Commando

We're going with space battles, and all three themes! Once again this is probably too ambitious for a team of 2, I guess we can't change our habits. Time to sleep now, have a nice jam everyone :)

The themes are MAPS, CHAOS and SHIPS, good luck to all! 2

Wan • 3 years ago on 10th Alakajam! 

With the theme now revealed, the 10th Alakajam! has started! Good luck to all! And consider supporting high scores for a chance to be entered in the tournament following the jam.

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: September 20th 7:00pm UTC, which means you have 48 hours (+1 hour for late entries to create their page).
  • Unranked: September 21th 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 ;)
