The game and editor are released under the GNU General Public Licence, although I would suggest that, if you make any improvements or modifications, that you send me a copy so that they can be incorporated into updated versions. The current version 4.0 integrates the game player and editor into a single seamless application, so there is now of course only one download. An episode can be selected using a graphical preview list, and immediately played or edited, without having to switch between two separate applications.
