DOOM-lite raycaster in your terminal. Pure [Phel](https://phel-lang.org/) (Lisp on PHP). 256-color ANSI, 10 procgen levels, FPS combat, ~5ms frame. Full feature list: [docs/features.md](docs/features.md).

Play
----

[](#play)

Needs PHP >= 8.4 and a 256-color terminal.

Fastest: grab the single-file PHAR from the [latest release](https://github.com/Chemaclass/phel-doom/releases/latest) (no clone, no Composer):

```
curl -fsSL -o phel-doom.phar https://github.com/Chemaclass/phel-doom/releases/latest/download/phel-doom.phar
php phel-doom.phar
```

Build from source (needs Composer, or Docker)```
git clone git@github.com:Chemaclass/phel-doom.git
cd phel-doom
make install
make play
```

Or `composer install && composer play`.

### No local PHP? Run in Docker

[](#no-local-php-run-in-docker)

PHP 8.5 CLI + Composer + deps in an image; `docker` is the only prerequisite.

```
make docker-build      # build image
make docker-play       # launch game (raw TTY)
make docker-test       # run test suite
make docker-shell      # bash inside container
make docker-clean      # remove image
```

Override tag: `DOCKER_IMG=mytag make docker-build`. Host PHP is the inner loop; Docker adds ~1s startup.
