Extra charge = extra damage (and extra CE spent). Releasing at charge ≥3 leaves a **lingering sphere** of attraction.\n- **Overcharged Red (HOLD to charge)** — release to blast; hold through the recoil to **rebound** it as a crushing physical hit that can Black Flash.\n- **🧨 HOLLOW NUKE** — fire an overcharged **Blue** that lingers, then fire **Red** before it fades → they **merge into a Hollow Nuke** that vaporizes the target (massive damage).\n- **Infinity** — a stronger guard in awakened form.\n\nThe interface:\n- **HOLD** the Blue/Red button to charge (a fill bar shows charge level).\n- **Release** to fire at that charge.\n- When a Blue sphere is lingering, a prompt appears — fire Red to trigger the merge.\n\n## The roster\n\n| Sorcerer | Style | Notes |\n| --- | --- | --- |\n| 🥊 Yuji Itadori | Pure melee | Every move is physical — the best Black Flash user |\n| 🐺 Megumi Fushiguro | Mixed shikigami | Melee summons (Divine Dogs) can BF; Nue is ranged |\n| 🔨 Nobara Kugisaki | Full ranged | Can't Black Flash — that's the tradeoff |\n| 🌀 Satoru Gojo | Ranged + Awakening | Rebound Red can BF; blindfold-off unlocks Maximum Output + Hollow Nuke |\n\n## File structure\n\n```\nindex.ts ← Hono server (serves the frontend)\nfrontend/\n root.tsx ← HTML shell\n index.tsx ← React entrypoint\n components/\n App.tsx ← UI: screens + combat engine\n data.ts ← Roster, enemies, moves, Black Flash rules\n```\n\n## Editing the game\n\n- **Characters / moves / bosses** — edit [`frontend/components/data.ts`](url:frontend/components/data.ts)\n- **Black Flash odds** — `BF_CHANCE` (0.08) and `BF_MULT` (2.5) in `data.ts`\n- **Screens & battle UI / logic** — [`frontend/components/App.tsx`](url:frontend/components/App.tsx)\n\nSave any file and Val Town redeploys instantly.\n",[],[76],"83e0cc94-a059-4ba9-9562-b0a0e332e0b4","CHANGELOG.md","01a0a53c-47b2-77dd-bce2-3d0b98040573",["D",1789478586214],"# Changelog\n\n## 2026-07-30 — Immutable asset caching\n\nFrontend files are now served at version-addressed URLs\n(`/__immutable/45/frontend/index.tsx`) with\n`Cache-Control: public, max-age=31536000, immutable`, so repeat visits load the\nwhole client graph from the browser cache — roughly 3× faster (~665ms → ~157ms\nmeasured). Publishing your val bumps its version, which changes every URL, so\ncaches invalidate automatically. Old-version URLs return 404 after a publish\n(like Next.js build assets); a reload picks up the new version.\n\nWhat changed in the template:\n\n- `frontend/index.html` → [`frontend/root.tsx`](/frontend/root.tsx): the HTML\n shell is now JSX and stamps asset URLs with `immutableFileUrl()`\n- [`index.ts`](/index.ts): serves `Root()` at `/`, and one\n `app.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path))` route\n serves all frontend files\n\n### Upgrading an existing remix\n\nYour copy of this template doesn't update automatically. Two options:\n\n**Minimal (most of the benefit):** point both routes at `serveImmutableFile` —\nyour existing bare URLs redirect into versioned space, the new route serves\nthem, and the whole module graph gets cached (costs one redirect per page view):\n\n```ts\nimport { serveImmutableFile } from \"https://esm.town/v/std/utils/index.ts\";\n\napp.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path));\napp.get(\"/frontend/**/*\", (c) => serveImmutableFile(c.req.path)); // was serveFile\n```\n\n**Full upgrade (also removes the redirect):** three self-contained steps —\nno other files needed. Adjust the ``, favicon, and body of `Root()` to\nmatch your app's existing `index.html`, and stamp anything else your shell\nreferences directly (images, css) with `immutableFileUrl()`.\n\n1.
