Many bunnies. But still no game :) demos.blit386.dev/bunnymark You can also try the software-rendered version, which has no #WebGPU bunny limit: demos.blit386.dev/bunnymark?em... #ScreenshotSaturday

Nine months on one game engine. 320×200, 256 colors. Still no game. I wrote about why I built BLIT386 anyway, and why the constraints that make it fun to use are the same ones keeping it from rotting. vancura.dev/articles/all... #gamedev #webgpu

BLIT386 1.7.0 – the performance release. The engine's hot paths no longer allocate per frame; the Canvas 2D fallback now clears a frame 69× faster. Plus reduced motion support, window.BT for devtools, and F9 to screengrab a frame. blit386.dev/blog/perform... #gamedev #WebGPU #a11y

BLIT386 - BLIT386 1.7.0 - nothing left to collect

The performance release - the per-frame allocations are gone from the engine's hot paths, plus reduced motion, window.BT, and F9 frame capture.

BLIT386 1.6.0 – the plumbing release. Every scaffolded game now talks to a live docs MCP server instead of guessing from stale baked-in docs. Plus a CSP nonce on the site and a symlink hole closed in the kit. blit386.dev/blog/mcp-rel... #gamedev #WebGPU #AI

Check this out. The loop rotating the hypercube never stops. Edit a method body and BLIT386 swaps it into the running game – ticks, camera, palette, palette effects all survive the swap. Only touching init() or the constructor forces a re-init, otherwise this gets hot-reloaded. #gamedev #hotreload

Certainly WebKit. There is nothing else on iOS, so I can’t test here.

BLIT386 @blit386.bsky.social · 15/08/2026

It’s working quite well! :) Take a look at the palette demos. However, I found a bug today that causes one demo to be stuck, which makes me nervous. I’m on a biking trip, so I hope it’s just a WebKit/iOS bug and nothing more serious.

First more sprite features, Aseprite support most probably. Then performance, and perhaps tiles. Somewhere in between framebuffer support.

And, yeah. I replied from a wrong account :)

Docs and blog are at blit386.dev, the rest of the demos at demos.blit386.dev. Follow along – there’s a lot more coming :)

A port of the classic macOS Flurry screensaver – 800 particles spiraling around twelve invisible gravity wells that trace slowly drifting figure-eight paths. Since BLIT386 has no additive blending for glow, it’s faked entirely through palette animation. demos.blit386.dev/flurry

Swapping the active palette recolors the whole sprite at once. All four palettes keep the sprite’s colors at the same slot numbers, so the swap is a single paletteSet() call – no per-pixel work, no re-indexing. demos.blit386.dev/palette-swap

BLIT386 Demo – Palette Swap

Switch the active palette at runtime to recolor an entire scene without touching the drawing code.

A rotating tesseract – a four-dimensional cube projected down to a 256×256 canvas, Fez-style. Grab it with mouse or touch and spin it like a trackball. The four line colors drift slowly around the hue wheel as it turns, so nothing ever looks static, even at rest. demos.blit386.dev/hypercube

No redrawing, just a palette swap. Water starts flowing, day turns to night, all from a few bytes. WebGPU with a 2D canvas fallback when the browser doesn’t have it. Check out some demos: demos.blit386.dev‬

I’ve been working on BLIT386 for a couple of months now – a palette-first retro engine for the web. The idea: you draw with numbered colors instead of RGBA, so redefining what color 3 means recolors everything drawn in it, instantly. #screenshotsaturday #gamedev #indiedev #webdev #TypeScript #WebGPU

BLIT386 1.5.0 – the random release. Seeded PRNG, coordinate hashes, three kinds of noise: same seed, same world, every time. Plus every easing curve and a palette fade that behaves like a camera iris. blit386.dev/blog/random-... #gamedev #WebGPU #proceduralgeneration

Modern engines gave up indexed color. That is the one thing I wanted back, so I built BLIT386. Draw with palette indices – change what color 3 means, and water flows, the sky goes dark, nothing redrawn. TypeScript, WebGPU, Canvas 2D fallback. blit386.dev #gamedev
