Here's an alpha release of Caves of Golorp, my new Roguelike game: golorp-0.0.1.tgz (393K). That includes both Prolog source code and a precompiled binary that works on my Linux system, for anyone who wants to play the game without compiling it themselves. It's released under the GNU General Public License, version 2. To compile it yourself you will need SWI-Prolog 5.2 or later. I really mean it about the "5.2 or later"; don't install an earlier version from a Debian package and then come whining to me about it not working. With the SWI-Prolog Windows compiler it should be possible to run this under Windows, but I haven't tested that. Any reasonable Unix should be no problem.
