We have added new items to the system save data and implemented additional features utilizing Windows functionality. To distinguish this from an official version update, we have decided to release it as a Beta version.




Note 1: Windows OS only
Note 2: Not available in borderless window mode; it can only be used in windowed mode.


Note: The Beta version is a test version that may include potential bugs due to major updates or other changes.
While we have conducted internal testing before release, please refrain from updating if you are concerned about possible issues.


If you wish to revert to the official version, follow step 3 and select "None" instead of the Beta option.

This update introduces a critical data protection system for save data, so we have decided to release it as a Beta version, separate from the official update.



With this feature, the folder icon previously displayed on the title screen has been removed. In the unlikely event of save data corruption, players will no longer need to manually restore save data from a backup.


This adjustment addresses an issue where players with low-resolution displays could not adjust the vertical height of the window, providing a solution for such cases.


This update improves a situation where players had to interact with the ending replay popup unnecessarily if they did not adjust depth after clearing the game. A countdown of approximately five seconds will appear in the popup, after which it will close automatically, and players will return to fishing. If you wish to view the ending replay, please press the OK button during the countdown.


This is an enhancement of a previous update. While most achievements were addressed, some remained unhandled. This version ensures all achievements are covered.


Corrected the wording for hidden conditions of some achievements.


Note: The Beta version is a test build that may contain potential bugs due to major updates. Although internal testing has been conducted, please refrain from updating if you are concerned about encountering issues.


If you want to revert from the Beta version to the official version, follow step 3 and select "None" instead of Beta.

Note: Automatic translation may result in slight differences in wording from the original text.
