+
+## Quick Start
+
+The easiest way to play is to visit the [online demo][demo]. It is more or less identical to the desktop experience at this time.
+
+While I do plan to have desktop builds released automatically, the game is still a work in progress, and I'm not quite ready to start uploading releases.
+
+However, every commit has build artifacts, so you can grab the [latest build artifacts][build-workflow] if available.

-- More than 4 ghosts
-- Custom Level Generation
-  - Multi-map tunnelling
-- Online Scoreboard
-  - An online axum server with a simple database and OAuth2 authentication.
-  - Integrates with GitHub, Discord, and Google OAuth2 to acquire an email identifier & avatar.
-    - Avatars are optional for score submission and can be disabled, instead using a blank avatar.
-    - Avatars are downscaled to a low resolution pixellated image to maintain the 8-bit aesthetic.
-    - A custom name is used for the score submission, which is checked for potential abusive language.
-      - A max length of 14 characters, and a min length of 3 characters.
-      - Names are checked for potential abusive language via an external API.
-  - The client implementation should require zero configuration, environment variables, or special secrets.
-    - It simply defaults to the pacman server API, or can be overriden manually.
 
 ## Build Notes
 
 Since this project is still in progress, I'm only going to cover non-obvious build details. By reading the code, build scripts, and copying the online build workflows, you should be able to replicate the build process.
 
+- Install `cargo-vcpkg` with `cargo install cargo-vcpkg`, then run `cargo vcpkg build` to build the requisite dependencies via vcpkg.
+  - This is only required for the desktop builds, not the web build.
 - We use rustc 1.86.0 for the build, due to bulk-memory-opt related issues on wasm32-unknown-emscripten.
   - Technically, we could probably use stable or even nightly on desktop targets, but using different versions for different targets is a pain, mainly because of clippy warnings changing between versions.
-- Install `cargo-vcpkg` with `cargo install cargo-vcpkg`, then run `cargo vcpkg build` to build the requisite dependencies via vcpkg.
 - For the WASM build, you need to have the Emscripten SDK cloned; you can do so with `git clone https://github.com/emscripten-core/emsdk.git`
   - The first time you clone, you'll need to install the appropriate SDK version with `./emsdk install 3.1.43` and then activate it with `./emsdk activate 3.1.43`. On Windows, use `./emsdk/emsdk.ps1` instead.
     - I'm still not sure _why_ 3.1.43 is required, but it is. Perhaps in the future I will attempt to use a more modern version.

     - `caddy file-server --root dist` (install with `[sudo apt|brew|choco] install caddy` or [a dozen other ways](https://caddyserver.com/docs/install))
 - `web.build.ts` auto installs dependencies, but you may need to pass `-i` or `--install=fallback|force` to install missing packages. My guess is that if you have some packages installed, it won't install any missing ones. If you have no packages installed, it will install all of them.
   - If you want to have TypeScript resolution for development, you can manually install the dependencies with `bun install` in the `assets/site` folder.

 So, I ended up using `unsafe` to forcibly cast the lifetimes to `'static`, which was a bit of a gamble, but given that they essentially behave as `'static` in practice, there wasn't much risk as I see it. I might re-look into my understanding of lifetimes and this in the future, but for the time being, it's a good solution that makes the codebase far easier to work with.

+## Implementing Cross-platform Builds for Pac-Man
 
 Since the original `rust-sdl2-emscripten` demo project had cross-platform builds, I was ready to get it working for this project. For the most part, it wasn't hard, things tended to click into place, but unfortunately, the `emscripten` os target and somehow, the `linux` os target were both failing.
