Oh,There is one more thing, the new version instinctively cannot stop losing the previous save. Although I can play the plot again, I still want my save more
:)
Yeah, Renpy and handling a lot of changing variables ain't too great. It can be done and by now I have an idea on how to handle it, but that will require me to rewrite large chunks of code (which I plan to do once I finished the next update).
Hopefully this makes save-game compatibility more easy to achieve, but even if not we'll have another alternative starting-point with the start of act 3.
