Simple snake game written in C using ncurses.
You can run it using
make run
Then do
./snake
This was the biggest C program I'd written so far, so I'm pretty happy with it. There's a separate frontend and backend so theoretically it could be easily extended to have a graphical frontend instead of a ncurses frontend, but I'm unlikely to actually do that.
There are also unit tests, which require checkmk to work.
