My pleasure. Yes, saving and loading will be very important. Save often and use multiple slots. ;)
Well the versions can be a bit confusing. The original game has its own versioning which reaches far back in time.
Be aware that the Advanced version will receive major content updates later. It is an extension I do on my own in my free time and it is a tremendous amount of work. Therefore I add content as episodes. Right now there are 3 finished episodes, hence the version 1.3x. I am working on the 4th episode right now, which will have version 1.4x. But it will only add content to the late game, so feel free to play. You still can finish the game without the new content of course.
