well i remember looking at this like 2 years ago, how is it now?
Map has changed a little, as in new buildings were added but the landscape is the same.
Capture system reworked to include "surprise sex" as an option for those who can be bothered to look up the milk/cum list for each creature (This can backfire, though, as they'll jump you too - and constantly. Personally I leave it off because of this.)
Cat-girls were added. Hybrids only. Not sure if we'll ever see a feral version.
Bat-girls were added. Like harpies but even smaller. They live in the cave behind your Titan dwelling. Again, no feral version.
Demons have a split off Succubus/Incubus subtype that is less scary looking (they use that terrible anime thing with bat wings stuck to their heads).
A glorious shit-ton of new hybrids were added. These can only be unlocked through breeding two different creatures together. They can't be found in the wild, only created on the ranch.
Special hereditary traits for creatures were added. Now they can be extra busty, extra fat, extra skinny, or come in weird bright patterns.
Sizes are now hereditary and can be changed thru breeding (<-- This is my new favorite part). Remember how you could never really fuck Harpies because there were no Normal-to-Small animations? Well, breed them with a Titan or Vulkwarg to make Normal sized offspring and bang away. Reverse is also possible - you can shrink those giant girls down to your own size to unlock
all the sex positions, now.
They added a Kracken girl for those who are into pegging/play-as-female who will shower you in good old fashioned tentacle rape, but only the one (she's a static NPC, not a roaming creature type).
2nd most awesome thing is that somewhere along the way DH discovered optimization and so you can actually play it without your view flying all over the place due to graphic lag. Runs pretty damn smooth, in fact.
New fast-travel mechanic called "Pussy Portals" (it's a porn game, man, whaddaya want?) that somewhat reduces travel times. They're not perfect but it's a good start.
