Oh my... that unconscious feature is so extremely hot. You really got the increasing sleepiness when applying the sedative and the confusion when waking up perfectly!
Be aware that it has some quite odd effects when used with the poser machine as the body & head get impossible positions for a short time when switching between the position presets when the girl is unconscious. On the other machines it seems to work quite well.
The serum cheat table is a really great idea, much better than using the cheat menu for each type and so intuitive, nice job.
I also love how well the breathing animation is implemented. And the improved costume of the catwoman (or batwoman?) is also very nice.
I'd really love to have the fucking machine available on the devious machine, too. I imagine that it's too difficult to add to the ring machine and the poser machine as they are too variable in the positioning of the girls, but the devious machine is even more stationary than the X machine.
Addendum:
When changing the girl while a serum is active the serum never stops counting down and the count gets negative. Instead the serums should be reset when changing the girl.
