Then just go ahead and stream live show. Set speed to fast, set missionary pose (before 0.60 worked flawlessly haven't tried doggy since it gave less with 0.61 yet) and keep mashing F. If you can get you're hands on auto-clicker set it to keep pressing F, through "on-screen keyboard". You will start seeing white thunders on screen, it means it's working
One run like that will get you easily 50-100k depending on how many parts you have equipped on doll.
You can also try stock market, its not so risky as you think but it's slow unless you farm up money in first place.

This game is slowly but steady getting there, it has enough content right now to leave impression and opinion, but it's really bare bones. The most you can get with story and romance part are in 4 mayor places : email box, talking with doll,church and clicking on TV, since after status showed up, it forces for an event to pop up.
Incontinent Cell, is doing god's work with this game. It's worth the wait and support.
