Your terminal must have at least 8-bit color. If enough people ask I'll make a black-and-white version. The window must be at least 50x22 cells large.
Grab a pre-compiled static binary over on the right if one matches your system. There is also a manpage for game rules as well as mode info.
# if you do not have ncurses installed...
# Ubuntu/Debian: `apt install libncurses5-dev`
# OS X has it preinstalled, otherwise: `brew install ncurses`
# Red Hat/Fedora: `yum install ncurses-devel` OR `dnf install ncurses-devel`
# Arch: `pacman -S ncurses`
git clone https://github.com/the-phi-project/snake
cd snake/
make
./snake
# if you choose, you could move the `snake` binary to /usr/bin/
# or /usr/local/bin/ to create a global binary, in which case
# you could omit the `./` above# COMING SOON!
