🕹️ THE VIBE JAM IS BACK! I present you... 🌟 2026 @cursor_ai Vibe Coding Game Jam #vibejam Sponsored by @boltdotnew + @cursor_ai Start: Today! Deadline: 1 May 2026 at 13:37 UTC, so you have a whole month to make your game! REAL CASH PRIZES: 🏆 Gold: $20,000 🥈 Silver: $10,000 🥉 Bronze: $5,000 RULES: - anyone can enter with their game - at least 90% of code has to be written by AI - it should be started today or after today, don't submit old games - game has to be accessible on web without any login or signup and free-to-play (preferrably its own domain or subdomain) - multiplayer games preferred but not required! - can use any engine but usually @ThreeJS is recommended - NO loading screens and heavy downloads (!!!) has to be almost instantly in the game (except maybe ask username if you want) - add the HTML code on the Google form in the reply below to show you're an entrant - one entry per person (focus on making one really good game!) WHAT TO USE: - anythign but we suggest @cursor_ai's Composer 3 and @boltdotnew, they are both fast, affordable and great at ThreeJS and making games THE JURY: Me, @s13k_, and I will ask some real game dev and AI people to jury again too Sponsors and jury suggestions still very welcome, just DM me! It will be interesting to see the difference in quality with last year, and the Vibe Jam can be kind of like a fun benchmark for AI coding seeing it close in on real commercial games I think To enter, complete the form in the reply below this tweet!

#vibeJam Day 9! Updates: Tough day for progress, despite putting in the time. Spent the day moving the holotable from confined to the table to a full centerpiece, since it's where the action will take place primarily. 1st screen - concept 2nd screen - start 3rd screen - current 4th screen - grid => sector shift diagram Part of the change toward more command oriented gameplay is shifting down from coordinates on a grid to sectors, which are 5x5 grids of coordinates under the hood. This will limit the number of POI's the player has to interact with and move closer toward "commander issueing orders to captains who carry them out". This is a huge change and taking it on all at once led to me just ditching the last several hours of work and reverting to a semi clean, mostly functional state. I'll spend a little time having codex and Claude tighten up the code base and implement a few code preferences, add additional unit testing, and now that I've got a greater handle on what needs doing hopefully give direction that orients the agents a bit more clearly and possibly in smaller chunks. Before the revert it was squash one bug, introduce three more, so best to step back and make it work better at first rather than bolting issues on top of broken code. More progress tomorrow for sure though.

Over the weekend, I added multiplayer "paint ball" dogfight to Tiny Skies, so players can fly around pelting each other with colourful paint balls, just for fun. I tried meshy and tripo to generate some 3D models for the game and the mesh vertices count are really high and lags the game a lot (probably because my game is a globe with thousands of objects - albeit mostly instanced). To my surprise, I found Gemini 3.1 Pro to be really quite good at generating good looking 3D models that are low in poly count. It generated 3D models at a much higher quality than Opus 4.6, Sonnet 4.6 and GPT 5.4. You can see the upgraded biplane models and some objects in the video below. #vibejam

Three Piñata is now available on Three.js Roadmap!🪅 It was freely available before, but this makes it a little easier to find. Trying to slowly gather all of my open-source stuff into one place... threejsroadmap.com/assets/three-p…

#vibeJam Day 8! Updates: - Added roll to ship movement & smoothed turning - Multiplayer works - Improved bridge flight simulation - Added scaffolding for sounds and first sounds with @ElevenLabs . Thanks @chongdashu for pointing out their skills! GPT, as it turns out, makes a banger of a @suno prompt also. First "space exploration" ambient track in place. You can hear a small clip in the attached video. - Tuned model builder. Still iterating. Got my first model I will use in the game (pictured). Observations: Using the model builder is much faster for iterating on simple models than trying to prompt toward it. Claude Sonnet is also, so far, the clear winner. Way more than GPT it simply tries harder - taking screenshots, comparing, saying when it screwed up, and then trying to fix it. I stepped in and moved one shape (the plinth) to get the final look, and the editor made it way easier than trying to guess with numbers or nudge with language. I've put together a skill but haven't had a chance to do a test with and test without yet. Tomorrow. Gameplay: I'm building out a bigger console because I think I'm nudging toward nixing a few of my original gameplay ideas and instead incorporating them more naturally. A game that was formative for me growing up was Mech Commander, and I can still hear Hitman, Falcon, Beast, and Lynx giving status updates and screaming "My armor's coming apart!" and while I won't be able to get that level of performance with Eleven (probably), I can still get the experience of a ship reporting in and giving cues on battle through audio. I want this to be very much a command experience, where the player participating in the combat is spice. So orders will be streamlined to be less like StarCraft and more like Majesty: Fantasy Kingdom Sim, with captains making choices on their own but overall under the command of the player.
