Well, truth in advertising here. It's an othello-type game where instead jumping into vacant spaces across lines of other colors, you jump from any of your spaces within 2 to an empty space, and every enemy color surrounding it is taken. The game is played with the mouse against the AI, although there's a command-line ("-t") option to start a 2-player mode.

The program exits at the end of the game, and displays a message it was programmed by "CatFace" but I've kept the original attribution (presumably the author's actual name) as that is how it was tagged in the NeoKobe archives.
