The warden mires, the artillery stifles, the leech unknits. All three need contact, so a survivor that kites cleanly takes none of them — debuffs punish positional failure rather than taxing existence. isOn/factor are written as arithmetic rather than comparisons: Math.min(1, Math.ceil(t)) is 1 while a timer is live and 0 once it expires, so consumers multiply instead of branching. The whole status module therefore contributes zero branches, which is what makes the 100% gate affordable for a system this cross-cutting. Statuses are applied unconditionally too; a 0-duration spec is a provable no-op. applyStatus uses Math.max, so re-applying refreshes rather than stacks. That caps a horde's total lockdown at one duration by construction — a structural guarantee, not a tuned number. 123 tests, 100% coverage. Branches 117 -> 119: the draw halo gate and the snapshot chip filter. The status logic itself adds none.

Reverse Survivors
Vampire Survivors, inverted: you are the horde. An AI-controlled survivor kites, auto-fires, and levels up on its own. You spend a regenerating pool of souls to spawn grunts, call escalating ring waves, and — once the seals break — summon bosses. Kill the intruder before the 5:00 clock runs out, or watch dawn break on your defeat.
Play
npm install
npm run dev
- Rusher / Stalker / Tank / Bomber — single spawns at a random arena edge.
- Wave N — a ring formation around the survivor; each call grows and costs more.
- Colossus (unlocks 1:00) and Hivemind (unlocks 2:00) — expensive, on cooldown. The Hivemind births free rushers while it lives.
- The survivor gains XP per kill and rolls an upgrade per level (damage, fire rate, speed, vitality, regen, multishot). Time favors it. Pressure early.
Where enemies appear is deliberately not yours to choose — the director picks what and when; the seeded RNG picks where.
Quality gates
npm run check = typecheck + lint + tests with coverage. All three must pass; CI runs the same.
| Gate | Enforced by |
|---|---|
| 100 % lines / branches / functions / statements | Vitest coverage.thresholds hard-set to 100 — the run fails below it |
| Strictest typed linting | ESLint 10 flat config: typescript-eslint strictTypeChecked + stylisticTypeChecked, @eslint-react strict-type-checked, react-hooks (compiler-backed rules), react-refresh, vitest plugin, --max-warnings 0 |
| Strictest compiler | TS strict + noUncheckedIndexedAccess, exactOptionalPropertyTypes, verbatimModuleSyntax, erasableSyntaxOnly, noUnusedLocals/Parameters, and friends |
Pinned stack (live-latest at build time): React 19.2.8 · Vite 8.2.0 · Vitest 4.1.10 · ESLint 10.8.0 · typescript-eslint 8.65.0 · TypeScript 6.0.3.
Why not TypeScript 7? TS 7 is the native (Go) compiler and does not expose the JS compiler API that typed linting needs —
typescript-eslint@8.65caps its peer range at<6.1.0. TS 6.0.x is the newest compiler that still type-lints.
Architecture (what makes 100 % honest)
src/core/— the whole game as pure-ish functions over a plain state object. Deterministic: seeded mulberry32 RNG lives in the state; same seed + same action sequence ⇒ identical run. Behavior dispatch uses records instead of switches, and clamping usesMath.min/maxinstead ofif, so there are no unreachable defensive branches to fake-cover.src/render/draw.ts— draws onto a minimalCtx2Dstructural interface; tests assert against a typed stub. (This layer's tests are mock-assertion ritual, as warned — the assurance lives in the core suite.)src/ui/— thin React shell. The rAF loop clamps dt to 100 ms and holds its callback in a ref.Appaccepts abootprop as an explicit test seam to reach both endings without simulating five minutes.src/main.tsxis covered too, including the missing-#rootthrow, viavi.resetModules()+ dynamic import.
