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

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

The random release – a seeded PRNG, stateless coordinate hashes, three kinds of noise – plus the full easing curve library, a splash that doubles as a loading screen, and an exposure-curve palette fad...

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
