Saddly, yes.
The problem I have with that is I need to add some conditionals and when an old savefile need them, the version have not those conditionals and then the game crashes ( Could I explain that understandable? I know my English sucks at so many levels)
For future projects, I'll try to make conditionals and decisions at first, and then work in the text and pictures of the game trying to prevent this issue.
But now, this project just need another version to be finished, so I'm afraid to tell that old saves won't work properly in 1.7.
I'll upload a savefile to start in act3 and I'll do one with all hentai scenes unlocked.
Thanks for your patience!
