The Sorrowvirus (Watchmaker) is a first-person adventure in which you must unravel the mystery of the Sorrowvirus. It is a substance capable of bringing you back to life by preventing your soul from reaching the afterlife. However, this gruesome story will teach you that immortality is the worst of fates.

Wyatt Hyell is a poor young man who has been hunted by illness since childhood. His parents will inoculate him with the Sorrowvirus to prolong his life and buy time investigating a cure. That causes Wyatt to suffer his death over and over again.


After living and dying many times, Wyatt’s mind has fragmented. He hardly knows who he is, what is true and when he will end his suffering. To help him, you will have to find out which of the four endings is the true one.


The Sorrowirus must be completed in one sit. There are no save points! The game will remember how many times you have finished it. Every successful run takes around one hour and influences the dialogue, the environment, the challenge and the ending.


To unravel the mystery of the Sorrowvirus, you must unlock all four endings. In each of your attempts, you will see how everything changes. For example, the notes with clues characters leave you will be different from run to run.


Values delivered

EastAsiaSoft is one of our most regular partners. Once again, they trusted us with the porting process of The Sorrowvirus to all consoles. Therefore, we brought it from computers to PS4, PS5, Xbox One, Xbox Series and Nintendo Switch.

Our mastery of Unreal Engine allowed us to achieve optimal performance in all of them. We also included notable improvements in the next-gen. For example, hyper-realistic 4K environments for the much-needed immersion in a narrative game.

Unreal Engine is the most powerful 3D technology on the market. No other software offers as much realism in its textures, shaders, lighting and effects. Unreal Engine is ideal for virtual reality (VR) experiences thanks to its superb graphic options. For this and many other reasons, it has become the engine used by most triple-A studios. Beyond its power, Epic Games’ technology stands out as one of the most intuitive when it comes to prototyping. All thanks to Blueprint Visual Scripting, a feature that allows programming without code. With these virtues, it is not surprising that almost 8 million developers choose Unreal Engine. As for Catness, we have been using it for nearly a decade. Thanks to that experience, every game we work with, no matter its size, will have the resources to look like a triple-A.

We at Catness Games have specialized in Unreal Engine since our first day. Although we can work with engines like Unity, we prefer to focus on what we mastered over almost a decade. Thus, we can offer the most optimal results. It is a matter of quality, transparency and honesty.

Catness Games bets on Unreal Engine because we mastered it. We have been developing, porting, and publishing video games powered by Epic Games’ engine for over a decade. We know that we will help you quicker and more efficiently if your game is #MadeWithUnreal. Thus, we prefer to be honest. However, we can also work with Unity. Our team has several programmers specialized in this engine. Besides, marketing is one of the core elements of publishing, but it does not depend on any particular technology.

The recent rise of virtual reality (VR) in the video game industry has not gone unnoticed. We acknowledge the potential of this technology. For this reason, we have already worked with it both in video games and architecture. Although we have more experience with traditional platforms, we guarantee the same efficiency with a VR project. Of course, the same can be said with augmented reality (AR)!
