I eventually managed to compile this on WSL after Googling a few cryptic error messages (I know rather less than an addled egg about this), and I’m just starting to play the game. (If someone produces a working Windows executable, please speak up. I was able to run the MinGW version of gfortran without errors, but the executable segfaults when I try to run it.)
It seems to lack some of the polish of Adventure so far, but I’m having fun exploring. The game takes place in a castle “somewhere in eastern Europe,” and you’re told that your goal is to find and kill the master of the castle. Meanwhile, in the very first room, you find a crucifix and a silver bullet. So it’s easy to guess what sort of person the master of the castle will be. Interestingly, this first room is a bedroom, and you start the game in the bed. All sorts of questions suggest themselves about this situation. How did we get here? If there’s any information about the player character, I haven’t found it yet.
LOOK works as expected, but there’s no EXAMINE. There’s a VERBOSE command, but it doesn’t seem to work - I have to keep LOOKing to get the full description of visited rooms. SAVE creates a file called CQUEST.SAV and exits, while RESTORE reads this file. Managing multiple save files requires renaming the files manually, and CQUEST.SAV is overwritten without warning on every save, so be careful.
