Curses is an interactive fiction computer game created by Graham Nelson in 1993. It was originally developed on an Acorn Archimedes using Acorn C/C++, before Nelson moved to his Inform programming language, which was simultaneously released. It was the first non-test game developed in the language. It is distributed without charge as a Z-Code executable. Writing for the New York Times, Edward Rothstein described the game as "acclaimed." The Inform source code is not publicly available.
