A version of Snake programmed for the Game Boy. Binary download and browser-playable version available on my website.
I built this project on macOS. The instructions should be pretty easy to follow from most UNIX-y operating systems. Windows users may have some troubles with the build scripts.
The build pipeline has a dependency on node.js. You'll need to install it. You'll also need to install RGBDS.
cd into builder/ and run npm install.
cd back to the project root directory. Run make. The output will be in bin/. Also note that the build process will generate asm files in img/. You can look at, but not modify, those files (they're rewritten every time you build).
