For those that want to cheat:
I will NOT admit to doing this, there is NO proof I have done this, I hope things don't change because maintaining mood and energy can be a pain.
Yes giving Alice multiple massages is a HORRIBLE torture. Repeating SEXY fun events with Kira is a chore. Lisa's Homework is difficult and frustrating. But these will help raise stats and I have FAITH that everyone can endure the torments of massaging Lisa and Alice.
To be honest the ONLY things that you MIGHT need to cheat are the mood of the Ladies, Energy, and maybe how clean you are. Money is a maybe (but not really) as well, but you need to be careful.
Hope this helps.
P.S. In the future cheats some cheats might be useful (like adding Spiders to the inventory might be useful, but for now it's not hard to just look for, and catch one).
P.P.S. I do not know what cheating relationship levels will do to the game. I haven't tried to do that, and there are enough opportunities to raise this stat that I doubt it will be needed. Try at your own risk (and tell me if anything good happens).
