Update Content: 1. Optimized the English and Japanese localization. 2. Regular bugfixes and optimizations.
- A Statement About Ending Early Access - 12 August 2020
Thank you for your constant support! The EA4.0 version of Mysteria~Occult Shadows~ was just updated. And there has been a bifurcation between the developer - U-Secret Studio and us on whether the EA4.0 version has reached the standard of a formal release. As a product provider, what our customers want and need has always been our priority. It is required that our point of view should always be aligned with you. After some in-depth testing by our quality assurance team, we've come to an agreement that there's still a pretty big gap between the quality of the current version (EA4.0) of the game and what the customers expected the game to be. So it is our duty to advise the developer that the game, at its state right now, is not ideal to be released as a formal version, that they need to work more on optimizations and quality control. But meanwhile, as the publisher, we also fully respect…

- Recent Thoughts on Future Update - 15 June 2020
Hey guys! Long time no see! As we gradually reach the end of the whole development, we've only got a few more steps to go. The script is one big update away from finished, which will include the final boss and ED animation. We've done making the final boss and are optimizing the details. Though we're somewhat short-handed, we would like to present to you an optimized version, which would be EA 4.00. This last update will take place some time in July. Here's a wallpaper from me for you guys to thank you for supporting us.
