This game didn't get much attention if at all any but nonetheless a fun
puzzle game that keeps you thinking. The game was discontinued at the
author's request. On August 19, 2005, the author herself released the
game as freeware though oddly she only released the Windows port but
you can also download the DOS port elsewhere as both ports are
freeware/abandonware.

Note: Both ports are the full Deluxe version that include the editor.
Enjoy.
