Rhythm Heaven never misses a beat

I need more of the original article text to complete a proper rewrite. The excerpt provided contains primarily contextual information (release date, series history) but lacks the substantive content needed for a factual rewrite.

Please provide the full article text, including:

- What "Rhythm Heaven Groove" is and what it contains

- Any verifiable facts about gameplay, features, or development

- Named individuals involved (developers, producers, etc.)

- Any specific quotes from Nintendo representatives or developers

- Sales figures, review scores, or other quantifiable data if mentioned

Once you provide the complete text, I'll strip editorial framing like "isn't Nintendo's best-known" and rewrite it as pure fact reporting.
