What it solves

The gap

An action run needs readable foes, fair bosses and a hook that keeps every room interesting, not just bigger numbers.

What it is

This template makes the weapon itself the decision: grow, spend or protect it, with grafts that change the rule and a bot with human-like settings to measure balance.

How you use it

Unzip, serve the folder and open index.html, then edit game.js; npm test plays it again in headless Chrome.

Source code of a real, playable game to reskin and learn from, with a smoke test whose bot plays it.

Who it is for

Use it when

  • Publishing your own top-down action or roguelite game on itch.io, web portals or your site.
  • Learning how a complete real-time action run with bosses, upgrades, a daily mode, run saves, a menu standard and tests is built in plain JavaScript and Canvas 2D.

Built for

  • Web and indie game developers who know some JavaScript.
  • Developers who want a finished, tested game to build on instead of a blank canvas.

What you get

The living blade

THORN_CAP, REACH_PER and DMG_PER set how the blade grows; dash() spends the thorns as a volley; hitPlayer() snaps half of them onto the floor to gather back.

Grafts

Each graft is one line in GRAFTS; its effect is read where thorns grow, fly or snap, so a new graft is a few lines in one place.

No build step

Plain JavaScript and Canvas 2D with no runtime dependencies; open index.html through any static server and edit game.js.

Tests included

12 unit tests of the core (growth, the volley, snapped and spent thorns, grafts, rooms and bosses, the lesson room, the daily thicket, run saves), 66 headless Chrome checks (keyboard, mouse aim, gamepad, phones by touch, grafts, autosave and Continue, menus, saves, sound levels) and a smoke test whose bot plays a run.

Questions

Make and sell any number of your own games from it, and build games for clients. You may not resell or share the source code itself (PN Scripts Template Licence 1.0).

Any static web server to run the game, and some JavaScript. Node.js 22.12 or newer and Google Chrome run the tests.

No ad or portal SDK, and English only. It is tested in desktop Chrome and phone-sized Chrome viewports with touch (held sideways at 915x412, 844x390 and 750x342; upright shows a turn-sideways hint), not yet on iOS Safari, Firefox or a real phone.

The code was written with AI assistance and checked by PN Scripts with automated tests. All visuals and sounds are generated by code; there are no AI-generated image or audio files.
