Hello from Studio BBB!

One week after launch, we're ready to share MONOWAVE's first update. We've refined wall jumps and movement in the air, and fixed progression blockers in boss encounters and hidden stages. The update also brings new colour vision filters, clearer Codex and menu layouts, and improvements to co-op play and sound.

Your detailed reports, screenshots and videos have been a great help in finding the causes of these issues. Thank you for taking the time to share them with us.

1. Controls and Movement



1.1. Wall Jumps







1.2. Running and Jumping





1.3. Movement with Sorrow







1.4. Keyboard and Controller





2. Progression and Co-op Play



2.1. Progression Blockers



We're sorry to everyone who was unable to continue because of a progression issue.





2.2. Returning from Hidden Stages

3. Display and Accessibility



3.1. Brightness and Colour Vision Support







Adjust the filter and strength to see how the colours change in the preview.

If your existing brightness setting falls outside the new range, it will be adjusted to fit the range the first time you launch after updating. If the screen looks different, readjust it under Settings → Graphics → Brightness. If you were already using Colorblind Mode, your previous filter is retained. You can select the new filters under Settings → Graphics → Colorblind Mode.

3.2. Aspect Ratio and Display





4. Codex and Menus



4.1. Codex Entries and Achievements





Existing Codex entries and earned achievements are retained. Previously missed Codex entries will not be filled in automatically, so please transfer the emotion again in the relevant stage.

The Russian cutscene Codex before and after the changes. Expanded the description area and adjusted text size and paragraph structure.




Enlarged the illustrations and descriptions in the Emotion Spirit introductions, and adjusted spacing and line breaks for easier reading.
