What the developers have to say:

Why Early Access?

“I am an indie game developer operating as an individual. This project features entirely original designs, and its development cycle is extremely long, with various upgrades and iterations expected in the future.

The project was originally planned to launch during the development process to gain support. However, the game encountered critical decision-making errors regarding performance and operations. The launch was too early, and effective feedback was not received during the internal testing phase, resulting in a suboptimal experience for users. I hereby formally apologize to all users. The developer remains committed to updating the project, and I look forward to your continued support.”

Approximately how long will this game be in Early Access?

“This is a content-driven title with a long-term update cycle. The Early Access period will continue for an extended duration until the content is sufficiently comprehensive.

During development, we encountered data loss and corruption issues. We also needed to address user feedback regarding game performance. During this period, we were occupied with redevelopment and asset reconfiguration, and were unable to provide progress updates.

The game is currently in a rebuilding phase. While we have restored some functionality and assets through data recovery technology, we are also fully aware of the issues that existed at launch. Therefore, the game is starting anew, with many features reworked. The Early Access period will continue long-term. We fully understand that development is significantly behind schedule and that we face the challenges of extended development time. We ask for your patience and welcome positive, constructive feedback.”

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

“This is a content-driven title with long-term updates. Content will be gradually improved over time, and we have already planned accordingly in our game rework. During the Early Access period, we will continue to refine features and game content. Once the features are basically functional, we will provide ongoing support through the full version.”

What is the current state of the Early Access version?

“On August 11, 2026, we officially began a one-month maintenance plan. We are currently using Unreal Engine 5.7, integrating existing publicly available assets, and combining individually developed and performance-tested gameplay modules into a reintegrated build. We are currently finalizing certain details. During this period, we will release two free DLCs in August for users who have already purchased the game. We will also accelerate progress on fixing major content issues.

Since the scope of work is essentially approaching a full redevelopment, some issues from previous versions are expected to be resolved gradually in upcoming updates. Features and content will undergo significant changes, and we hope you look forward to them.”

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

“As a content-driven project, maintaining long-term updates without relying on in-app purchases is a significant challenge for us.

As content gradually improves, we will progressively increase the price once we have a stable, regular update cadence. As the creator of this work, I sincerely thank all users who supported this project in its early stages.”

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

“After our major content maintenance is complete, we will release our derivative works policy.

Derivative creations will play a vital role in keeping our community active and are our greatest hope for community engagement.

We also encourage VTubers to stream content related to this game. Plans for this will be tested internally after major content maintenance is completed, and then made public.

As the creator, I sincerely hope to see derivative works of my game in the doujin community in the future. I would like to thank all creators who may create derivative works of this project in advance, and I hope you will reach out to me when you publish them :)

Thank you all for your support. :)”

About This Game

※(2026.08.11) Currently, the main content of this game is under maintenance, which means that purchasing the game at this time will not allow you to experience the main content. Please be fully aware of this. During the transition period from maintenance to gradual rollout, we are providing playable DLC at no additional cost; however, you must own the base game to access these DLCs.

Since the game's launch, we have received a large number of reports regarding optimization issues, while also facing the loss and corruption of some data files. Development progress has now been restored, but because our approach to optimization issues has been module-based (or focused on individual gameplay features), it will still take some time to merge these data sets.

The main content is divided into the "Visual Novel" part and the "World" part.

The "Visual Novel" is implemented as a non-interactive 2D experience. Based on the current development schedule, it is expected to go live as early as September 2026. Please note that the visual novel is structured in episodic, multi-chapter format, meaning that users will not be able to make route choices, nor will there be character romance routes. This visual novel serves as the core of the entire game project, and the "World" part that players engage with is built upon its worldbuilding and settings. You can think of it as the history of what has happened in this game world—much like reading a light novel or web novel.

The "World" part will integrate "Blueprint of Miracle" with another previously unpublished work, and it is the central gameplay component for players. The gameplay for this part is currently being consolidated and will be updated progressively. The team aims to restore player access to the "World" part by August 2026.

Until access is restored, please enjoy the DLC :)
