You can update your DRM-free copy to the latest version at http://www.thecatlady.co.uk/updates

The page contains information about changes & which save games will be compatible.

Note: Due to the nature of the updates and the AGS engine, It is highly likely that they will NOT be compatible between your GOG version and the new version 1.4. However, you can un-install the update and re-install your original copy (version 1.2) to play your old save games (so you may want to back them up).

If you have any problems with the update let me know.

Thanks for posting here about the update Mark! Quick question. Your list of changes includes:

Expanded OST included in folder "OST"

Does this mean you've simply included more of the game music as separate music files, or have you expanded the music in the game?

Hi there, sure - more music (roughly 20 mins worth) is included as separate OGG files. Nothing in the game has been altered. regards!
