+# Feely Pona (aka. Terry Cherry)
+
+This is the repository for the game Terry Cherry that was developed as part of
+an impromptu game-jam in September 2023 over 4 weekends to make a hero
++ tower-defense mashup combination game. The game was developed in C++ using
+Raylib 4.5.0 as the base framework for the game.
+
+This game was developed with 3 people
+
+- Doyle:     Engine & gameplay programmer
+- Joshalosh: Game designer, sound, gameplay programmer
+- Tom:       Art
+
+This game is currently available online at [Terry
+Cherry](https://game.doylet.dev/terry_cherry).
+
+## Building
+
+We target Windows and the web via WASM using Emscripten. The game is built
+using our C++ meta build program (which generates command invocations and
+forwards them to the command line).
+
+### Windows
+
+You must ensure you have MSVC's `cl.exe` on your path to build. This game was
+tested on MSVC 2023 (v14.34.31933).
+
+For most intents and purposes you may simply execute `build.bat` on Windows
+which bootstraps the build program and automatically calls the meta-build
+program. With fast computers nowadays our default is to build all targets by
+default (except web due to extra toolchain requirements).
+
+### Web
+
+A web ready version using WASM can be built by passing `--web` to the meta build
+program/script. You must have the EMSDK toolchain activated and in your path
+from [Emscripten SDK](https://github.com/emscripten-core/emsdk). This repository
+provides a slimmed down version of EMSDK in the `Tools` folder zipped up and
+served over Git LFS.
+
+The slimmed down EMSDK is the official download with a bunch of unused binaries
+and directories removed that aren't strictly necessary for building the web
+target (e.g. provide a stub Java version file to skip it, delete unused clang
+binaries).
+
+Unzip the slimmed down EMSDK `Tools/2023-10-10_emsdk_40e9cd8f.7z` or install
+from Github and download the latest SDK. A full build for the web target can
+then be done by
+
+```
+# Run EMSDK's script to add the toolchain to the path
+Tools\emsdk\emsdk.bat activate latest
+
+# Build the game
+build --web
+```
+
+This will produce at `Build\Terry_Cherry_Emscripten` a HTML and WASM file ready
+to be served by the browser. To test it locally you may start up a local server
+for that directory, e.g.
+
+```
+cd Build\Terry_Cherry_Emscripten
+python -m http.server
+```
