What it means for players
The trailer supplies visual context for previously announced systems, making it useful for planning future guides without treating edited footage as proof of exact values or routes.
This update narrows one specific player question using the publisher’s wording. It does not turn unreleased footage or marketing copy into invented routes, values, schedules, or performance claims.
What remains unconfirmed
Natsume has not announced a public demo, review build, or complete unedited gameplay session.
