Thanks for the question, and the feedback.
For the save game issue, I'll see if i can investigate and patch in the next version. The cache is there when I play of a lot of my games, which shouldn't be the case with a new build.

Still not an expert at Ren'py, if I can't figure it out, I can post on their forums to see if people have ideas (or here if people have them).

What's new?
This is the "1.0" version; all final maps, two new animations with Victoria and a new finish series with her, a clone series as well as numerous bug fixes & more.
For the last three weeks, I've been busy learning new Daz3d tricks, testing out content and doing some design exploration for my next game.
Let me know any and all bugs that you find so I can add them to my backlog for the "1.01" release next week.

Daz3d, Iray render set to 1280 by 720 - usually the external daylight(s) these days also with an extra 3 light setup. Sometimes postwork (tone / brightness auto) in Photoshop to adjust details, or fix small things. Usually I try to avoid post render work if I can so it saves time.
