- 👻 Happy Halloween! 🎃 - 31 October 2025
Hey hey! 👋Today is Halloween, the time of spooky ghosts and creepy skeletons... and partying in cool costumes! 🎃To commemorate such a cute moment, here's an artwork of them surprising yet another neighbor. How could you resist giving them all the treats!?Art made by Uruka (X)On our left, the shy girl is Yuko Kanbayashi. She actually has cat ears even without the costume, since she's a neko girl! She didn't feel like dressing up too much, so she is a cat girl in a cat hoodie. She loves playing indie games and sleeping (even when they all hang out). She's also currently the most tech-savvy girl of the trio!On the opposite side is Misaki Fujiwara - both in position on the artwork and passion for costumes! She loved creating costumes so much that it stuck with her to this day, and her main passion became fashion and costume design! She's also the one who gave Unity-chan her nickname.And i…
- Mod Toolset release and more modding features: skins, translations, scenery - 22 August 2025
Hey hey!It's been quite a while since I posted a devlog, but it was a busy time! The good thing is that the work has its results, and I managed to prepare UCDC Mod Toolset to a state ready to be public! Yeah, even before there is a game to be modded, you have access to mod it :DUCDC Mod ToolsetI prepared several public repositories to organize the Toolset:Releases - a place with unity package ready for download, and documentation focused on general info about modding. This is the most important place to visit if you're interested in modding the game GitHub - UCDC Mod ToolsetMod API - a repository containing code for a library that is used to communicate mods with the game. The library is included inside Mod Toolset, but this repository is good if you are interested in creating your own scripts in mods GitHub - UCDC Mod APIMod Templates - a set of mod templates. I decided to create quite…

Today marks a very special day - it’s Unity-chan’s birthday! 🎉 We all wish for her to become the superstar she’s always dreamed of being……Wait. Why is she going up? No, Unity-chan, that’s not how you become a star! Get back here before the balloons carry you into orbit! 🎈🚀Art made by MisuzuMeow, go check her other artworks on X A little update about game modding On a more serious note, I want to personally thank all of you for your support, we’re closing in on 800 wishlists!

- Modding Support in UC:DC - How It Works & What’s Ready 🔧 - 19 June 2025
Warning - this post gets into more technical stuff, focuses more on game's behind the scenes work and mod support structure. I assume the reader has some basic knowledge about how programming works. So if you're not into this stuff it may become complex or really boring! 😅Last time I mentioned that I'll focus on adding mod support to the game. In this post I'd like to show you the progress that I made and how it looks from the internal architecture side.At first i looked into how to add modding support to games. And the most popular advice was a bit stressing - the best way to add modding to game is... to design the game with modding support in mind right from the start of the project! 😫 It makes sense - if the game would load all resources from directories, all configs stored in text files then all would be much easier for others to modify and play with.But since I lack the skills of…
- Update about current work and future release - 22 May 2025
Hello! Today's post will be a bit different, as I'd like to tell you about my current struggles and plans for the future months. Some time ago, I decided to participate in the upcoming Steam Summer Next Fest. I applied, wrapped up all important tasks, and sent my game build for review by Valve team. Build verification is a standard procedure; Steam uses it to ensure that the game delivers on what’s promised on its store page and that it launches correctly. But that’s where some problems began... After the first review, my game was rejected. According to Steam, a game cannot require players to set up anything outside the game, such as creating external accounts or downloading additional tools. Additionally, in-game payments must be integrated with Steam's microtransaction system. These are fair requirements—Steam wants to ensure every game is playable immediately after installation, and…
- Unity-chan has even more integrations: Twitch, Music and Voice! - 18 April 2025
Hey hey! Another month of development has passed, and I've got some new features to show off! First off, I'd like to thank all of you who are interested in the project and supporting it. Thanks to your suggestions and ideas, the game keeps getting better and better! 🧡🤎 If you'd like to get more involved in the development process, come and join our Discord Server! We discuss new features, chat about games we've played and share memes! 😀 Unity-Chan: Desktop Companion Official Discord Server! Twitch chat support 🎥 It was a feature I've wanted to add for a very long time. Since the initial inspiration for the project came from the Neuro-sama streams, I've always wanted to create a way for people to let their mascot interact with viewers in a broader way. For now, I've created a very basic integration - Unity-chan will occasionally read the chat and pick a message to respond to. But tha…
- Unity-chan room rework and another Wishlist milestone! - 20 March 2025
Hey hey people, JacopoDev here! Here's the stuff I worked on since the last devlog! 😎 Finishing what was previously started Last month I started with finishing tutorials for self-hosted AI API integration, I added new YouTube videos showing how to set up the KoboldCpp and Ollama connection. I also created GIFs and added them to the steps of the step-by-step Wizard to make it easier for anyone to prepare the text AI. https://www.youtube.com/watch?v=FOTE4UtVuRA More YouTube materials 🎥 I also worked a bit on reaching a wider audience, I created a few YouTube short videos showcasing some game features. But most importantly, I had my very first interaction with media creator, GameDevJourney! They asked me a few questions about my development adventure, and made a post about my game with my answers! Go check it out and share! 😁 GameDevJourney site And here is the short that got most views…
- New stuff: self hosted AI, translation support, and lots of bug squishing! - 20 February 2025
hey hey! 👋 Another month, and another pack of cool new things that has been added to the game. This time I focused more on technical aspects of the game: language translations, additional API for text generation, and lots of bug fixes! 🐛 Language selection is now supported! This time, as planned, I added the support for the translations. Now at the start of the application for the first time, there will be an option to select language. As the first language I added... polish! Mainly because it's the language I know best, so I didn't have to look for proofread. Now I may tell that my game has truly became polished, heh. But thanks to adding the translation support, other languages will be much easier, will mostly be about just filling the column of texts with proper translation. Of course, there may be some issues with languages like font support, or proper spacing... but that's the pr…

Thank you for your support and Happy Valentines Day! ~Jacopo
- Meet new boss character in Virus Offense minigame! - 10 January 2025
Hello in 2025!
- Virus Offense (mini) game rework, and some other stuff too! - 21 October 2024
While I was planning this month's work I originally wanted to create yet another mini game, but after playtesting I decided to focus more on improving the existing mini games so they would feel more complete. And so I added a brand new game mode to Virus Offense To recap, what is Virus Offense? Virus Offense is one of mini games you can play in Unity-chan: Desktop Companion. It is a top-down shooter, where you and Unity-chan fight against corrupted safety drones and viruses in the cyber-space! The game itself can be accessed via Unity-chan's TV game console, after entering her room and clicking on sofa. So, what's new? The games has new game mode. For now I named it just Main Mode, but maybe I'll change it in the future. The mode is inspired after roguelite games like FTL, Slay the Spire, Peglin, where the player has a map made of nodes, and we travel through them to reach the boss. Nod…
- 100 Wishlists! Thank you 🧡🤎🧡🤎 - 10 October 2024
Unity-Chan: Desktop Companion has surpassed 100 Steam wishlists! Thank you everyone for believing in my project! I will keep on working and improving the game. I will add new community post summarizing new features in a week or so. In the meantime, here is the art I commissioned to celebrate the wishlist milestone! Art was made by MisuzuMeow (X profile)
- New Feature allows Unity-chan to comment on any game you play! - 18 September 2024
Hey hey, I have new cool things to share! 🧡 While I was planning what new features I should add to the game I came to conclusion, that my pace of creating mini games is too slow for them to be a full-fledged part of the game, and they may quickly become boring for the players. The answer would be to create games that have infinite replayability, and while it's true, this type of games also need a lot of time of development to become complete. So I came up with an idea - what if I made so Unity-chan wasn't limited only to mini games created by me? After all, Unity-chan is a mascot of a game engine, it would be fitting if she reacted to other people's work too. And her name is all about uniting things, it all made sense so much I couldn't pass up on this idea! And that's how two new features have emerged: 1. Register ANY game into Unity-chan's Game Station. 🎮 2. Control Unity-chan envir…
- What I've done!? - 10 September 2024
In previous post I described what in general idea Unity-Chan: Desktop Companion is. This time I will show you all of the features that were implemented so far. Keep in mind that the game is still under development, so some of the features may be more polished in the future, and slightly changed. Also this post may spoil a little, so if you'd like to be surprised about what things may happen during your play through please keep that in mind, And sorry for lengthy post, but I wanted it to summarize everything, so future posts could focus on newest changes. So let me start from the beginning: 1. AI chat - ChatGPT 💻 Project has started as a basic console application, where I was playing with OpenAI's API for ChatGPT text generation model. After some playing I found that I am able to make it interpret message emotions, and based on it rate the current mood of the character. That's how I cre…
- Desktop Companion - What Does That Even Mean?! - 11 August 2024
Today I decided to tell more about the exact definition of the game, as it is not that obvious. I will also tell about the overall direction of game's development. But first of, since it is my very first community post, let me greet all of you Hello World~! 🧡 For starters, I think I need to answer some questions that will picture you the image of what Unity-Chan: Desktop Companion is, and what can you expect from it. So, What is Unity-Chan: Desktop Companion? The shortest answer would be: It is a Windows desktop virtual pet with AI chat and mini games. The full answer is more vague, as the game itself is a blend of various game genres. I define three major directions this game takes during development: 1. Sandbox: You spend time with Unity-chan exploring game features, playing mini games, hanging out in her virtual room and casually chatting with her. 2. Utility: Using advanced GPT AI…
