hi ! i got some issue here. after trying different resolution in order to get a proper one, the game end up like this. i can't click on anything except the the config in the middle . how to reset the resolution? 
There is not way to reset resolution in game but you can try editing registry.
- In search bar type regedit.exe. That will open Registry Editor.
- Now navigate to HKEY_CURRENT_USER/Software/LAGS/Lustful Spirit Hunt.
- You should see some values on right side. Look for a value looking like this 'Screenmanager Resolution Height_h2627697771' and 'Screenmanager Resolution Width_h182942802'. Delete those values and close the window. Your resolution should be back to default one.
