Ren'Py / VN

Curse of the Night Stalker [Ch.5 v1.0] [AncalagonSlayerDesigns]

September 30, 2025F95

In this AVN you take the role of Valtier, a hunter and forager for a small town. During a hunt, he is bitten by a vampiric snake and begins to undergo the symptoms of vampirism. This leads to increased bloodlust and sexual lust, which in turn, begins to impact the people around him even while he tries to live a normal life.
You will manage his daily life, maintaining various supplies while keeping suspicion low. Meanwhile, you must decide whether to resist your vampiric nature to protect the women around you from becoming your thralls, but becoming your lovers by their choice. Or corrupt them further into more depraved acts, bringing them closer to an eternity of sexual servitude.

Chapter 4

First off, I just have to apologize to my paying patrons;, as there is an error in a corrupt choice with Phoebe, – which you may have run into, that I missed because I went back to it and added to a sound effect there but forgot to test it. You may also have found a missing image during the Nyrobi scene at the end; actually shot_35_ns doesn’t even exist so I was just bad at counting, so you weren’t missing anything at least. I’m very sorry for this sloppy work, I was so concerned with getting Chapter 4 out before April ended, that I didn’t review fully and properly like I usually do, and I messed up. So, sorry for that. There is actually an in-built script checker for Ren’py which I have used before but completely forgot about before the release of 1.0, like I said sloppy work. Thankfully, I have now fixed those problems, so at least no-one will have to worry about that cock-up again, make sure you download this version and leave 1.0 for the burial grounds.

I have also managed to reduce the file size down by about gigabyte, without skimping on the image quality. I didn’t even touch Chapter 4 images yet, so I could reduce it down even further. Hopefully, worrying about keeping the file sizes below 5GB for the AVN’s future is over, and you won’t have to hear me complain about that ever again.

I have also redone the first ever Mira scene, as that one has been annoying the hell out of me for ages now. I finally had enough time to just go back and redo it and bring it up to Chapter 4 quality, which is nice. I might do the same for the rest of Chapter 1, but the other scenes are not as dire as that first scene, so probably not. Maybe a few choice images here and there.

Finally, I have changed the text to something a little nicer and easier on the eyes. I did intend to try and create a dark mode for the text that you could toggle on and off. But that turned out to be far more complicated than I thought it would be, particularly in Ren’py, so I have shelved it for now. Maybe some other time I will manage to get that done, but it’s not super important.

Chapter 3

Well here it is, as always thank you all for your patience, support and time. As you’ll see, the file size is much bigger, due to switching to PNG images over JPGs for Chapter 3. This really makes the colours and visuals pop a bit more and it is the best-looking Chapter by far. Along with the PNG switchover I also have a much better method for post-image processing (a.k.a. photoshopping; but it’s done in GIMP, so is that gimping instead?) which has helped improve the visuals. I have also gone through Ch.1 and used this process to improve those images, along with brightening up a lot of them, and they look much better. I’ll also do this to Ch. 2 images at some point so everything will look much better in the future.

I’ve also separated the music and long sound effects, as originally these were both being played through the music channels (there are 2 on Renp’y by default), but now I have added the long sound effects into the sound channel and the small sound effects can be played either through the sound channel or the voice channel. What this means, is that you can much easily adjust the music and sound effects individually and freely to your liking for any scene. You might think that I should have had this included from the start, but the voice channel was a little weird and I had to play around with it to get sound effects to go through them. But now it is done.

Chapter 2

Hello everyone, I’m happy to release Chapter 2 to the public, please see the attachments below for v1.1 of Chapter 2 which has a few visual tweaks and upgrades to Ch.1 images as well as some spelling and grammar fixes that slipped by me last time. I mentioned in the paid subscriber/patron release that I wasn’t going to upload this version now to the public because of upload space limitations, but that has been resolved.

Chapter 1

Initial Release

Developer Notes:

Here are the attachments for the first release of Chapter 1 of my very first project. Consider this a demo of what I will be capable of with more experience and money, as I aim to make this my full-time job and life’s work, so expect things to get better as we go. Prior to making this AVN I had no prior programming or 3D model manipulation knowledge and have already learned a lot. My priority right now is to save up for a PC (as I am doing everything of a laptop right now), as this will improve render quality substantially, with a PC I can also then start learning to use Blender to create fluid animations in the future. So I hope you enjoy this maiden voyage, and thank you for checking out my work.

The PC version has a corrupted image. Just download the Hotfix and merge the game folder.
