You need a game build or source code and a free human text to play. All builds require a keyboard to play. Place everything for a build and a human text file named snayk.json in the same folder to play. For source code, you must build, then place snayk.json in the same directory as the build to use. Once you have it set up, double click or whatever the default open is on your platform the game build. The source code is in English in Rust language, to build for your system, install Rust, then in the root of the source code, in a terminal, run "cargo build -r", tack on a target that is not your current if desired. The game includes many options like gradient colors, expand mode, option for show bounds, number of dimensions and their sizes, and how many things to eat which increase your score and if not in expand mode, increase your size by one. Be sure to read the controls section and click it to expand in the game, then go near the bottom and play game. The game automatically saves your current state when you close except with crashes. Put something in the last string, set of quotes, of the human text to reset every time that human text loads, keep it empty otherwise. Note that by default, you are purchasing a single machine license per purchase.
Note that the last string in the file resets the game to defaults and start menu if anything is placed in it. Contact me at This email if you found an error or want a new language. Please suggest what to change if you are doing that.
