v0.756.9

Since I have started working on a rewrite/redesign of the UI, I decided to quickly release the current build to the public.

The UI redesign is something I have been putting off for years, and it has started to interfere with development. Not to mention, the UI has been the target for complaints from players. The new design will make the game much less annoying, as well as open up development opportunities for me.

v0.756.8

I have been working on improving physics, and decided to release a WIP build to get some feedback. Saves were wiped in this build to fix some crashing bugs and reset physics data.

* Added dick physics, and the ability to control it via presets
* Preset physics settings now work properly
* Editing the breeder’s physics now takes effect immediately
* Tweaked engine physics settings for smoother simulations
* Fixed crashes involved with pregnancy and auto saving

v0.756.1

Moving to Unreal Engine 5 turned out to not be worth the sacrifice and development efforts. I may change my mind on this in the future, but for now I have decided to focus on adding content and optimizing the game in UE 4.27.

This build was dedicated to adding Lovense sex toy support, this is a first test before the next build which will be public.

* Fixed: Surabhi does not yield semen during harvesting

v0.755.2

While working on recovery and moving, I have managed to make another build. It’s been a difficult few months to say the least. Now that I have finished moving, I will continue trying to release builds as I can.

New in this build are vagrants, roamers for the ranch essentially. One can be set per barn. They can be interacted with in much the same way as wild roamers, but they won’t surprise you.

Added: Vagrant system

Tweaked: Tasks will now accept any trait rank

Fixed: Graphical bugs around the town fountain

Upgrade engine version to latest hotfix

Hotfix

Fixed: Blow jobs still used random winning conditions.

v0.754A

Here is a brief overview of the new system:

Stats are now ranked E-S.
Stat ranks cannot be leveled with breeding. Player needs to catch better wild Nephelym with better ranks.
Stats can rise by both leveling and breeding.
Rarity has been introduced, which affects stats, ranks, and traits.
Presets can now be restricted to rarities, so you can have legendary schemes.
Loyalty has been replaced with Excitement.
Excitement will decrease if no actions are performed per day. With enough excitement, stat gain from breeding and max lust is increased.
Most traits have been completely changed. See the tooltips for information.
Some traits are ranked: Bronze, Silver, Gold.
Removed traits that did not fit the lore and theme of the game: Abomination, Grungy, Gaudy, Sadistic (now Efficient).
Females now have access to exclusive Motherly trait for balance.
Releasing Nephelym now has purpose: it will increase the World Level for that race.
World Level governs the rarity of roamers.
Surprise Sex is now Wild Sex, gone is the need to repeatedly click. Rather, there is an automatic stat comparison that takes place.
Nephelym you house at the ranch will develop preferences for positions, variants, body types, and specific other mates.
Preferences are ranked: Enjoy, Like, Love, Worship.

Note on Languages

This first pass is crude, most of the UI cannot be translated yet and it will be a slow undertaking to expose it all. The only language available right now is simplified Chinese as it was generously contributed by patrons.

Soon, I will open-source translations so that anyone can submit them, but keep in mind as the game progresses more dialogue will be added/changed and translations will need to be updated.
