Hi,
We're happy that you like the game, there's no set way to play the game, everyone can enjoy playing as they like :)
Just few words of clarification:
- numbing lipbalm reduces the wakefulness gain when you use her mouth for blow job/kissing
- lubricant is a camera upgrade material - not meant to be used as an actual pussy or ass lube
- to use mouth or penis effectively, make sure she climaxes at least once - this will significantly reduce overall wakefulness gain
- there is also blanket strat for farming credits simply taking off and putting back on the blanket earns you credits, if you do it fast enough, it's also worth upgrading the camera's lenses and sd card to increase multiplier of gained credits and length of the night respectively.
Cheers
