Hello guys!
I don't know if someone has already written this so maybe I'll repeat myself. But I have a couple of tips:
1. if you chose the wrong dialog option you wanted you can go back using the 'Back' button at the bottom of the screen (Note: it has a limit on how many dialogs you can go back by)
2. If you only care about the erotic scenes, open (Windows only) the downloaded game folder then the 'game' folder and the 'images' folder. Main folder ' images' and ch04 folder contains animations and the others only images.
For Android: using the RAR application, open the downloaded .apk file (in RAR select open as archive) and enter the same folders as in Windows. By holding down on the folder you can extract it from the .apk file.
