(Open to all 18+ persons, no purchase necessary to enter)

If you like to be notified of when new builds are available via e-mail, there is now a system set up to do exactly that! Details on the research blog.
If you're already set up to get post notifications via Patreon, feel free to ignore this -- I'll still be posting short versions of notifications here, too. The main difference between my new e-mail system and the existing one for Patreon is that I can put the full build update notes and uncensored images into my e-mails, whereas with Patreon I'm not supposed to put uncensored images in public posts.

Timeframe (updated for Sept 2022)
This should happen within 1~30 minutes of you signing up, but may take up to three days depending on how lagged the data Patreon provides to me is.
If you need instant access, you can back the project through BMT (our other authorized retailer) via our website.
Private Game Builds Download Location
Link your Patreon account to the Researcher Portal, all game builds will be delivered there after payment is charged (see above notes regarding delivery timeframe).
Special note for Gift Code Users
Users who received a gift subscription from another user should contact me via Patreon DM, Forums, or E-mail right after activation as that process is manual. All other purchase types are automatic and do not require manual intervention.
Something went wrong?
First, verify you have a Patreon charge on the Manage Memberships > Billing History page. If the status is not marked as 'Complete', you have not yet been charged.
Second, have you linked your account to the researcher portal? It can take 30 minutes after linking for access to be granted, if you have a 'Complete' charge.
Finally, it may take up to 24 hours after the payment status being marked as 'Complete' for that change to be reflected in Patreon's API.
If you have verified the above and something is still amiss three or more days after a 'Complete' charge, please do reach out to me via Patreon PM, Forums, or E-mail.

You had seen the town whore around Haven plenty of times. A two-headed pink-scaled hydra, she had been affectionately named The Whoredra by Haven's populace. When you decide to give her a go, you get more than you bargained for when her pimp, Anica, offers a free fuck in exchange for working off the debt. Anica merges you into the Whoredra's body, making you into the third head of her whore. You're trapped in the body of a huge-titted, fat-assed draconic prostitute, and you have to share it with two other horny heads!
Manage the lusty desires of your fellow heads, or they'll wrest control from you and slut around town as they please. 26k+ new words of content.
Full update notes (and an awesome update image) are available on the research blog!

An early sneak peak of the Hydra is now available to WIP backers -- most players will prefer to wait for the full release though, as similar to previous WIP releases, this build contains no text. (See the research blog for details)

The Hydra DLC is coming along slowly but surely -- I ended up going a bit overboard with the logic on her, but I'm pretty excited about what it's shaping up to be! It will likely be one of the most technically complex transformations in the entire game.
In the meanwhile, please check out this survey on community discussion methods and preferred notification methods.

Chapter 7 is getting closer to complete, with all the code and gameplay finished for it. The next step will be to write all the text for the chapter. If you're a WIP backer, you can check out an early build of Chapter 7 -- but most players will prefer to wait for the full experience to be ready. Please look forward to it! :)
