Building something ambitious in a browser? Here's a playbook: 24 experiments, each testing one risky assumption before you commit. Every spike runs live on cinevva.com with source code. Wins, dead ends, and the two-day bug where the geometry was correct.

Your browser game will probably die the same way: beautiful concept, pretty scene, frame budget gone before gameplay. The fix: test the ugly question first. Can it hold 60fps with 500 objects? That baseline now powers Cinevva's shared open world. app.cinevva.com/blog/2026-02-2…

Should browser game physics run on the main thread or in a Worker? Rapier + WebAssembly, dedicated Worker. We measured it. Controls felt immediate. This pipeline runs in Cinevva's open world now -- feels like a native game, not a browser tab. app.cinevva.com/blog/2026-02-2…

We’re open-sourcing HY-World 2.0, a multimodal world model that generates, reconstructs, and simulates interactive *3D worlds* from text, images, and videos. Outputs can be integrated into game engines and embodied simulation pipelines. Key highlights: 🔹 One-click world

Building terrain streaming? Don't test with complex content from day one. When a 40ms stutter hits: decode issue? Upload stall? Geometry? Test simple first. Get a clean signal. This is why Cinevva's world loads from a URL -- you're moving before full detail arrives.

If your browser 3D world gets bigger by adding more geometry, you're heading for a wall. Geometry clipmaps: constant triangle count, any draw distance. This is how Cinevva renders a shared world in a browser tab. Same budget at your feet or the horizon. app.cinevva.com/blog/2026-02-2…

The BAFTA Games Awards just wrapped and this year's lineup says something important about where games are heading. Clair Obscur: Expedition 33 led with 12 nominations. A debut game. From a studio most people hadn't heard of two years ago. Sandfall… bafta.org/games

The BAFTA nominees share something AI can't shortcut. Real-time parries inside a turn-based RPG. A mansion that redraws itself every day. Branching narrative stapled to a hero-assignment sim. Mechanics. Systems. Rules. The part nobody can automate.

5 patterns from 24 open world experiments: • Test the scariest question first • Checkpoint before integration jumps • Test under motion, not screenshots • Measure per-feature, not averages • Publish the dead ends Try the experiments at cinevva.com

Want caves in your browser game? Heightmaps can't do it. Marching cubes on the GPU via WebGPU compute. No CPU readback. This is the tech behind terrain editing in Cinevva -- sculpt caves in your browser, watch the mesh rebuild live. app.cinevva.com/blog/2026-02-2…

If your world looks better every time the art team adds something, you don't have a budget. You have a wish. A real visual budget means the total cost is fixed. Every new prop, every tree, every effect has to earn its spot by beating something already… app.cinevva.com/blog/2026-02-2…

I can't believe we were right Claude was dumbified on March 4, just when we noticed!

In May 2022, I sat for a podcast interview and made some bets about gaming. WebGL would be a real game runtime. GPT-3 would land in production pipelines. Game tools would feel like Google Docs. The future would be indie. None of those were obvious in… app.cinevva.com/blog/2026-04-2…

Steam Next Fest is the closest thing to a free spotlight a small game can get. It's also frequently misread. The last festival: around 2,200 demos, and the usual pattern held. The games that did well during the week were mostly the ones that already… app.cinevva.com/signals/2026-0…

Rules don't reduce complexity in a game engine. They organize it. After chasing the same kind of bug in ten different places, we stopped reacting case by case. One central rule now decides, for every piece of terrain on screen, how detailed it should… app.cinevva.com/blog/2026-02-2…

What vibe coding a multiplayer game can look like ☀️🤩🌍

Cinevva looks like a single text field that says "Describe your game". That's deliberate. The prompt is the front door, not the product. Behind it sits an orchestrator with 26 typed tools, eleven asset providers federated into one search, a live game… app.cinevva.com/blog/2026-04-3…

For twelve parts of our open-world series we built a terrain engine you could look at. Fly over it. Admire the seams not cracking. This time we wanted to touch it. The goal sounded simple. Let a player sculpt the terrain with a brush, in real time,… app.cinevva.com/blog/2026-04-1…

Most AI game tools stop at "code into files". Ours runs the game. After every build, the agent is required to call read_console_logs and fix any errors before handing back to the user. That single rule eliminates most of the "the AI said it was done… app.cinevva.com/blog/2026-04-3…

After 13 parts of our open-world series, the terrain was working. You could sculpt it. Seams held. But it still looked like a tech demo. Debug-colored shading, wireframe overlays, grey geometry with LOD colors to tell chunks apart. You could edit it.… app.cinevva.com/blog/2026-04-1…
