Hello and good time of day =)
Using RenPy i created offline story/scene player.
Version bundled with toolset - guide
MEGA - old / GD - last version
But its limited by scenes unlocked on my account, so please, if you have missing character (red button color), please, send me scenario files of characters you have.
How to obtain scenario files:
1) Open game
2) Launch browser developer console (F12 for Chrome, Ctrl-Shift-I for Firefox)
3) Navigate to Network tab, set filter string _harem-
4) Start scene. Last loaded file is what you need. Open in a new tab and save.
Best regards.
