Sigilfen in play: a burning golden sigil closing round a crowd of foes on a dark low-poly fen

What it solves

The gap

A survivors-like needs hundreds of foes without frame drops and a balance that is easy to break with one weapon change.

What it is

A finished, tested survivors-like with capped pools and a spatial hash, whose balance bots replay on every test run.

How you use it

Unzip, run npm ci and npm run dev, then edit the config; npm test replays whole runs again in seconds.

Source code of a real, playable game to reskin and learn from, with its proofs built into the tests.

Who it is for

Use it when

  • Publishing your own survivors-like or arena game on itch.io, web portals or your site.
  • Learning high-count entity simulation and bot-based balance testing in TypeScript.
  • Building a branded action mini-game for a client.

Built for

  • Web and indie game developers who know some TypeScript.
  • Studios and freelancers who make branded browser games.

What you get

One config file

Rules and caps, the sigil, heroes, weapons and evolutions, charms, foes, the boss, waves, unlocks, daily modifiers, colours and sound.

Balance with a proof

On every npm test a kiting bot plays whole runs and must beat the boss, while an idle player must die early.

A finished game

Burning sigils, six evolving weapons, eight charms, a boss, three heroes and a daily night.

Tests and a guide

62 unit tests and Playwright browser runs, a size budget, an upload zip for itch.io or any static host, and a guide to adding weapons, charms and foes.
