Oh typos definitely need to be fixed, but I've caught a bunch already thanks to feedback, so hopefully I'll get them all by the time the patch rolls out.
All of that with the fight is intentional, except potentially the HP bit: as far I know there shouldn't be any change there, unless you're talking about the HP resetting to full when it loops.
One mistake that has been fixed at this point is that the Flash Dodge wasn't getting re-added on loops, so if you didn't win the first time, winning in the loops was a real pain. That's been fixed.
The shed bit is artistic license. The scale of the two scenes wouldn't allow it to work.
No jackoff scene. Was considered, along with a whole mechanic around draining lust so it wasn't a hazard in battle, but ultimately didn't make the cut.
