#js13kgames — Public Fediverse posts

@brianwdouglas indeed having a jam would be awesome, or to have a webxdc category in #js13kgames jam

I finally posted about my lastest js13k Games entry, Alley Kitty. It is mostly about technical stuffs and compression, but I am sure there are at least some who find these things interesting :)

I am working on a blog post about my latest js13k Games game jam entry, mostly from a technical perspective.

I always wanted to see the numbers for each part at each stage - I am finally making it!

(But it is a lot of work and lot of words 😅 , these charts are ready and are interesting IMHO, so I wanted to share them even if I never finish the blog post in the end.)

Alley Kitty, my game for the js13kGames 2025 jam is live!

>> Play: https://js13kgames.com/games/alley-kitty <<

Check out the gameplay:

The game is open source, as usual:

I should probably just stop adding new sprites and objects at some point - preferably really soon 😅

I am now at 9146 of 13312 bytes (68%), but there's still some space for refactoring and optimization, and I think I even can cut a few stuffs.

#js13k #gamedev #gamejam #alleycat #js13kgames

Slowly coming together with the details, now it is even playable (and kind of fun!), it has character animations, music, transitions and other goodies - it starts to feel like an actual game!

Currently at 55% of the size limit (7345 of 13312 bytes used), still a lot of stuffs on the to do list!

#js13k #gamedev #gamejam #alleycat #js13kgames #screenshotsaturday

After a late start a tiny game of a black cat might be forming after all :)

PS. there is still a lot to go but it might look familiar to some - that's probably not a coincidence.

Tons of prizes (100 t-shirts!), no entry fee, the challenge is to make a game in only 13kb! This jam has been around for over a decade. Join the fun. I am one of the #gamedev judges.

THIS YEAR'S THEME: "BLACK CAT"

#js13k #js13kgames And on the first day Rob said, “Let there be cat,” and there was cat. Rob saw that the cat was good, and he separated the cat from the nothingness.

I have submitted Hauntriska, my game for the js13kGames 2024 game jam!

It is by far not my best entry but it isn't the worst either. It's a short game about catching some ghosts and a funky storage unit that doesn't like the number 13.

Check it out here: https://dev.js13kgames.com/2024/games/hauntriska

I made it in about 14 hours, I haven't really optimized or used any advanced compression, it is 9441 bytes in the end.

So... I have worked for about 3 hours on my entry for js13kGames 2024 game jam and it looks like this.

How hard can it be to make a (good) game out of it in the next 23 hours and 39 minutes until the deadline? :D

#js13k #js13kgames abandoned my initial game idea, going to make a platformer instead

I realized you can never have too many of js13k Games t-shirts! That's why I made a game this year as well :)

#js13k #js13kGames #GameJam #GameDev

Today at 18:45: I think I got the concept of my game for js13kGames 2023!

And tonight I started to implement it. Hey, there is still 5 days and 15 hours left to make this from scratch. It's not completely hopeless!

#js13kgames #js13k #gamedev #gamejam #javascript #html5

#js13kgames starts in 4 days! I’ll try to keep an up to date dev log this time.

I’ll also be posting read-only posts on Twitter as they don’t have a fediverse presence yet. Please, follow me here instead if you’d like to reply to my posts.

Woohoo, the Js13kGames swag pack has arrived! It has a t-shirt, a lot of stickers, a coaster, an enamel pin, more in the alt text.

For this jam I made Cooking for Skully, a cooking game in hell where you play the chef (who happens to be the devil) and prepare tasty foods for your friend Skully.

It ranked #12 in Overall, #9 in Mobile, #2 in Server, #1 in Decentralized, #5 in Web Monetization.

That moment, when you realise that you just have overwritten all edits on the distribution file of the last couple of days 😰🙀

Luckily had a browser tab open so I could restore.

Now under version control and part of the build process!
