Hugo is one of the leading interactive fiction design systems. In addition to being capable of producing leading-edge text adventures, it also allows a developer to incorporate true-color graphics display (which are optional for those who lack either the hardware or inclination to view graphics) as well as sound effects and music. And it's free. This is the ncurses port, without support for sound or graphics.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
