A browser-based Star Castle–style vector siege: rotating energy rings with gaps, a central gun that shoots back, homing mines, inertia flight, shields, and a high score saved locally. Built with TypeScript, Vite, and the Canvas 2D API—no game engine, small bundle, runs anywhere you can host static files.
Fan tribute. Vector Keep is inspired by classic late-70s / early-80s coin-op vector games (including Cinematronics-style castle shooters). It is not affiliated with any rights holder, and it does not use original ROM assets, logos, or sampled audio.

GitHub Pages (this repo): Pushes to main run .github/workflows/deploy-pages.yml—npm ci, npm run build, then publish dist/. In the repo Settings → Pages, set Source to GitHub Actions.
vite.config.ts sets base to /Vector-Keep/ so asset URLs match https://vedjuk.github.io/Vector-Keep/. If you fork or rename the repo, update base to /YourRepoName/ (with trailing slash), rebuild, and push.
Other hosts: After npm run build, upload the contents of dist/ anywhere that serves static files. For a site at the domain root (not a subpath), use base: '/'.
