The gap
A metroidvania needs ability-gated rooms, persistent world state, bosses and a way to check that the whole map can still be finished after every change.
Game templates
The complete source of Burrowvane, a metroidvania-lite with twenty text-defined rooms, four movement abilities, three bosses, save shrines and a bot that plans its own route through the whole map.

The gap
A metroidvania needs ability-gated rooms, persistent world state, bosses and a way to check that the whole map can still be finished after every change.
What it is
This template gives a complete twenty-room map with abilities, bosses and saves, plus a bot that plays it from start to finish headlessly.
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.
Use it when
Built for
Each room is thirteen strings of twenty-four characters; edit a row to add a ledge, a root wall or a pool, and the renderer and the bot pick it up.
Thin roots need the dash, deep water needs gills and high shafts need claws or wings, so moving one pickup reshapes the route through the map.
Plain JavaScript and Canvas 2D; open index.html through any static server and edit game.js.
A headless Chrome test loads the game, checks the console, presses keys and taps, and lets the built-in bot play a run to its result screen.
