For now, the only option for installation is to build from source. Make sure you have the standard build tools (make, gcc) and also have the ncurses library. Once you are ready, simply run sudo make install.
A couple of options are available for you to tinker with in the config.h file, from simpler things like the controls, to modifying game constants. Just make sure to recompile after making changes.
