Is there a way to uncorrupt or go back? I accidentally slept and now I'm stuck with the corrupt cop TT
Also, is there anything else to do with the wife and daughter of Mario after that or should I just wait the next update?
You have to start a new game if you want to change any Route unfortunately.
As for Katarina, you can make her fall in love with you and sometimes you'll meet her at the Mall
As for Emma, you can have sex with her once a week ( Uncorrupted ) or have a threesome with Mario everyday ( Corrupted ).
But that is it for V1.3.
