Frequently Asked Questions
Quick answers for the rules and features that are most likely to be unclear during play.
I cleared 80%. Why did the service scene not appear?
80% is the normal clear target. The service scene unlocks at 90% BONUS.
What does 99%+ mean?
99%+ is the current PERFECT target. A literal 100% is not always the most natural grid result.
Are saves stored in an account?
No. Progress and settings are stored mainly in the current browser. Clearing browser data or changing devices can separate that progress.
Where do I change keyboard controls?
Open ⚙ OPTIONS → ⌨ KEY MAPPING. This affects PC keyboard controls only.
Which mobile orientation is recommended?
Landscape is recommended for a wider board and more comfortable control spacing.
I missed the Collection screen after Stage 10.
MY COLLECTION remains available for 72 hours on the same browser after completion.
Does normal feedback collect my name or email?
No. The normal feedback form does not ask for a name or email.
Why is there a 19+ notice?
The game contains non-explicit fan-service artwork intended for adult players.
