The #js13k 2025 #winners have been announced a few days ago already - let’s see the specific #criteria that comprise the overall #results, plus some extra #rankings about the voters in our community. js13kgames.com/2025/blog/cr... #gamedev #gamedevjs #indiegames #gamejam #HTML5 #JavaScript

The main takeaway from #js13k 2025: don't sink time into big, complex, self-contained concepts you don't have resources to finish properly. Start small but complete - then polish it as far as you can. Next year's goal: get the game to playtests and tune the gameplay from there 🚀

ZzFX sound was used by 6 of the top 10 JS13K games, including top 3 in audio, congrats! 🏆💤🚀 #js13k ZzFX is a tiny open source tool that can play sound effects like magic without needing sound files. What would you like to see in ZZFX 2.0? 🔊🤔 killedbyapixel.github.io/ZzFX/

All sounds & music in my #js13k entry Catapoolt were made in #pico8 🎶 Playing them on Web (desktop + mobile) was made possible thanks to the awesome 'pico8-music' library by Cody Ebberson - took a few tweaks, but totally worth it 🙌 Huge thanks for helping my game sound! 🔊

In my #js13k game Catapoolt, the “hard-to-catch” mice are actually Autonomous Agents 🐭✨ They roam the game field using wander behavior and evade the cat with flee behavior - straight from the fantastic #theNatureOfCode book by @shiffman.lol

Surprisingly fast decisions under #js13k limits: needed cat tail aligned to body. Instead of proper math - pushing tail's anchor along normal between two adjacent soft-body points towards center (super unstable), I just increased body outline thickness. Hacky, but perfect! 😶‍🌫️ #gamedev #indiedev

I wrote a blog post about my (unfinished) VR demo for #js13k using PlayCanvas. There were some tough but interesting limits to using it while keeping the game under 13 KB. https://blog.svntax.com/playcanvas-and-the-js13kgames-competition/

Just posted a mini postmortem of my #js13k entry 🐱💎 What went right, what went wrong, and how I crammed a kleptomaniac cat into 13kb 👉 eoinmcgrath.com/kleptokitty/... 🕹️ Play & rate KleptoKitty: js13kgames.com/2025/games/k... #gamedev #littlejs

LittleJS rendering system is crazy fast. For the procedural hills in my #js13k game, I just draw a few thousand thin vertical strips. No sweat. 💪🚂

There is another LittleJS game in #JS13K and it's fantastic! 🛩️💥🐈‍⬛ Black Cat Squadron by repsej is a one button shooter based on a real WW2 secret US Navy squadron. There are 10 levels with a final boss and you can continue! js13kgames.com/games/black-...

Here’s how the cat, the main character of the Catapoolt game for the #js13k contest, was made 👀 Big shoutout to Argonautcode, whose awesome tutorial youtu.be/GXh0Vxg7AnQ goes into detail on how to build a soft-body physics simulation #gamedev
