1) That in a porn universe/reality these things happen?... Also story development tends to be done last in porn games. Not everyone is always here for a story, just some basic plot.
2) Upping INT will slow down the slider making your DEX training that much easier to hit the red bar.
3) Relationships in porn worlds almost never happen. (Unless it's a dating sim.)
4) again, porn reality, normal rules of our reality doesn't apply. That or it's pre and mix of juices from the female. But mostly it's fantasy rules.
For a porn game, this is very good so far. More enemies, more access to further levels, unlocking the gallery, and yes more story is all that's needed now
