Personal Study [v.0.12] (2024) (Rus/Eng) [Unreal Engine] [ArcaneSpoon77]

v0.12 - 2026-04-02
Release Notes
Hello everyone! In this update, Evi begins exploring a new branch of the dungeon, which she can access through a newly added portal. To activate the portal, you need to talk to the imp.

This is a smaller update in terms of content. It adds a puzzle room and one H scene.

Additionally:
Fixed the input prompts that broke after the transition to UE 5.4. They now correctly display keys according to the key mapping in the control settings and also take gamepad keys into account.
Made small tweaks and fixes to some of the early cutscenes.
Reduced SSAO effect to fix visual artefacts in H scenes

v 0.11.2
Release Notes
Added two new outfits for Evi. One can be found in the fresco room, the other in the room before the garden. post_37.png
Reworked POV camera in H scenes.
Added POV option for all story H-scenes.
Partner Opacity is no longer tied to POV and is now controlled individually for each partner.
On first launch, the game will now attempt to match the desktop resolution. This should fix an issue where the game could start at an extremely large resolution on some PCs.
Several bug fixes.

v 0.11.1
Release Notes
The Priestess’s puzzle: The metal ball half that was in the Priestess’s room has been placed in the puzzle room, and also added a pattern for the second fog wall to the hint book.
Puzzle in the Garden: Increased the brightness of the glow around the character when the mushroom is in the inventory. This should better convey the intended way to solve the puzzle. Also slightly increased the movement speed of the moths.
Adjusted the controls for the Alchemy puzzle, it should be more intuitive now.
Removed the stabilization of view direction for the POV camera. The camera should no longer spin out of control when looking in certain directions.
H scenes from the ritual with the Succubus are now available through regular summoning. These scenes currently do not have climax animations.
The failed ritual event is now available for replay in demon form.
Several bug fixes.

v 0.11
Release Notes
Hello everyone! The new update is finally out. This update is focused on continuing Evi’s adventures, she will finally get the opportunity to perform a magical ritual with the Succubus.
To progress the story, you will need to interact with the bottle crate in the dead-end room after the final puzzle.

This update includes two new puzzles: one at the alchemy table (it will require some patience), and another in the mini-garden.

As for the H-content, there are new scenes featuring the Mimic, the Imp, the Guest Demon (he doesn’t have a name), and the Succubus. All scenes are event-based, and after triggering them, they can be replayed via the research diary.

You will notice that this update contains more words than action. This is not how I plan to approach development going forward, it just turned out that way this time. I will try to balance things the other way and return to a shorter release cycle.

I hope you enjoy the update!
Feedback and bug reports are always appreciated.

v0.10.1 - 2025-05-05
Hint system moved to Special Abilities. While active, Concentration mode highlights interactable objects, but slows down character movement.
As an experiment I changed tech behind cum stains. Now it’s texture overlay instead of mesh and stains have stages of buildup (three stages for every hole)
Added missing climax animations for Succubus.
Made some corrections and adjustments to constraints in Physics Assets of characters. Added jiggle physics in the thigh/butt area for Evi and Succubus.
Marked ‘north’ on the drawing to help with orientation while solving the last puzzle.
Bugfixes.

v0.10 - 2025-03-12
The door with ‘in development’ sign (in the hall before priestess encounter) can now be opened and it leads to a new puzzle room. Even though this puzzle is less cryptic, as an experiment I added an intermediate autosave between two logical parts. I think this approach could serve as a compromise between complete reset and saving every action.
Added H scene with succubus
After mimic scene added popup that tells player about Research Diary
‘E’ hint should properly remove itself after picking up figurines

v0.09.3 - 2025-01-21
Redone one of the animations with male summon on the table
All animations with male summon now have climax option
Added voice samples for new animations
Fixed several bugs
v0.09.2
Added minimap.
Added new voice samples for Evi in H scenes, there's a lot more variety now and less repetition.
Added localized version of intro (subtitles only)
Visibility of the text box in cutscenes can now be toggled via Tab key.
Improved shader and models for ice cubes.
Bugfixes
v0.09.1
Project moved to UE 5.4. With that I also had to make internal changes in the input system, which means that custom control settings will be reset. Other than that everything should function as before. Now you can use the gamepad to control character by default. However for UI navigation you still have to use cursor. It's ugly, yes, but adaptation of the game to the controller is an extensive task and this is the first step. You can change some key bindings in settings (look sensitivity also affects gamepad)
Added Evi POV in H scenes
Orbit camera now saves its last position before going POV so that it doesn't appear in weird places on switching back from POV to Orbit
After climax stains persist, there's Clean button now to remove them manually
Closed with geometry necks of summons when switching to POV
Added several hints in form of text in places where people get stuck the most
Black outfit now available in all replays
For replay of the last event I added options to watch only H scenes for both forms
Added research diary in succubus room so that players won't have to run back to the main hub
Added a small vfx around the character's head that signals when interactables become highlighted

v0.09
In this update I added a new puzzle room. This puzzle room is part of an event where Evi with the help of several new characters learns a new cosmetic ability (demon form, which was disabled in 0.08). To access it you will need a key that can be found in the last room of the planet puzzle. After you pick up the key, you will be able to open a previously inactive door in the hall with an area for summoning.
Event scenes can be replayed via Research Diary in the main hub.
Also:
Added optional slight camera shake in H scenes.
Added floor collision for camera.
When switching poses the camera doesn’t jump anymore.
Voice volume slider now works properly.
Fixed an issue with overlapping UI elements on lower resolutions (hopefully)
Other bug fixes.
v0.08
The project moved to UE5. This is mainly to have access to up-to-date development tools. I will not add raytracing or other such gimmicks. The only difference for the player is sharper image, because of the new default anti aliasing method.
Added a lot of sounds for interactable things and there's some ambient noises as well.
Added a small intro to give the player a sense of how and why MC got into these dungeons.
Reorganized some menus and added new icons.
Added save system. Players can make a save at special objects which are placed in rooms with summoning circles. The game also saves automatically after dialogues and solving puzzles. I should note that the system tracks only the status of puzzles (solved/unsolved), meaning if you move some objects and try to save, on load game will return that puzzle to its default state until you complete it.
Added missing dialogues and slightly expanded male summon ritual with HJ scene.
Removed Gallery mode. Since the game can be saved, there's no need for a special mode to view animations. But with that all content related to MCs demon form will be temporarily unavailable. I plan to reintroduce it in the next update, where MC obtains this ability.
Telekinesis now works more reliably and is less likely to push objects through walls. Also when you grab immovable objects, the camera stays in freelook mode.
If the character stays in place for more than 5 sec, all interactive objects are highlighted.
Reworked some parts of character locomotion.
Work on VFX. Mostly to adapt them to UE5.
Work on certain environment pieces.
Many bugfixes.

- Added H-scene with succubus (available only if MC is in demon form)

v0.05
I'm changing gameplay structure a little bit. The approach, where player obtains all the content by solving one complex puzzle, is not how it was planned originally. I've built it that way because I needed to make something in a short time to provide gameplay example as a concept. It is not ideal, but it allowed me to gather some feedback.

Now I want to remake level so that player will need to solve far less complex puzzle for every piece of content. Puzzle to acquire summon itself and then puzzles for scenes+items required for progression.
At the moment level contains sort of tutorial part, where I tried to explain the game mechanics, it's like 30 sec of gameplay.

When I finish with all the environment and first puzzle room, player after the tutorial section should acquire first summon, currently there's just an empty room.

For now all NSFW content moved to Gallery Mode and will be gradually added to the game.
-Added ability to pick up certain items directly, I'll try to reserve use of telekinesis for large objects and where it makes sense.
-Added new summon and 1 scene in Gallery Mode
-Added couple of graphics settings, that can improve fps

v0.04

For this update I worked on dialogue system, figuring out how I want to approach this. To test it I've added some sort of introductory dialogue with dummy npc. Hopefully, in the future I can turn that dummy into a meaningful character.
- Tweaks for some locomotion animations
- Added NSFW scene
- In scene menu added option to make partner transparent
- Added some sounds (still experimenting with scene sound, need good source for female voice)
- Fixes for SSS glowing artefacts, morph targets and other miscellaneous issues

v0.03
- Tweaks to some of the logic of puzzle part. It's basically the same, but now it should be less confusing. Hopefully, when I add a bit of narrative aspect to it, the puzzle should make more sense
- Added bunch of sounds
- Some work on the environment and props
- Tweaks to vfx
- Minor bug fixes
- No new NSFW content

v0.02
Small content update.
- Added new outfit for the MC (can be found on the table in hub area). I thought, it would be fun to have in the game outfits of various characters as some kind of collectable items
- Added 1 scene in the summoning circle, accessible through scene menu
- Added background soundtrack ( thanks to Umbra Nensei )
- Added option to start the game with content unlocked
- Some tweaks to reflections in the environment, hopefully with no major performance impact

v0.01
First iteration on gameplay stuff. As expected, it revolves around puzzle solving. I've built a room for activities, where MC's abilities can be actually used. It still needs some polishing, but at least it functions and represents the concept.

There's no new NSFW content, I plan to work on that for the next update.

Demo2
In this demo I've expanded ability of scene placement to utilize more environment stuff in the future.

- Added 1 scene
- Added option to change gender of the protagonist
The gameplay side of things is not addressed yet .
