What the developers have to say:

Why Early Access?

“We believe that by releasing the game in Early Access, we can gather valuable feedback from the community and make necessary improvements before the final release.
This ongoing development ensures that players will have new content and features to look forward to as they continue their journey in the game.”

Approximately how long will this game be in Early Access?

“The game is estimated to be in Early Access until at least mid-2025 or possibly until the end of that year.
Please keep in mind that we have a small development team consisting of only a developer and a writer.
While this means certain aspects may take longer to complete compared to larger teams, we are dedicated to delivering a high-quality experience.”

How is the full version planned to differ from the Early Access version?

“The full version of the game will offer more features, expanded content, and a polished experience compared to the Early Access version.
We value player feedback and will incorporate it into the development process.
Expect additional gameplay mechanics, enhanced visuals, and expanded storylines.”

What is the current state of the Early Access version?

“The Early Access version is currently in a good state. Seasons 1 & 2 feature over 11,800 renders and 400 animations.
We have made significant progress in developing both seasons. Player feedback is highly valued, and we are actively working on refining the overall experience.
Regular updates will be provided to enhance the game.”

Will the game be priced differently during and after Early Access?

“During Early Access, the game is offered at a discounted price as a gesture of appreciation for your support.
However, the price is expected to increase slightly upon the game's full release to reflect added features and improvements.”

How are you planning on involving the Community in your development process?

“We engage the Community by actively seeking feedback, suggestions, and bug reports to improve the game.”
