Small-size readability

• Contrast: blue mark on blue fill — check both dim OLED and bright LCD.
• Silhouette budget: number, rectangle, star, circle should remain readable after the store’s rounded-square crop.
• Lettering “9” must survive home-screen size; thin strokes usually fail first.
• illustration detail collapses quickly below ~60px — verify the 60px mental model before trusting the master.
• Internal usability score for this capture: 0.6/100 (heuristic, not a store ranking).

These checks are practical references for designers reviewing 魔法ピアノタイル9 : ピアノゲーム、おんがくげーむ、音ゲー, not authoritative store scores.

Transferable design moves

• Keep number as the primary silhouette before adding secondary ornaments.
• If the fill stays blue, push identity into a single geometric mass rather than a busy texture.
• This capture’s illustration vocabulary transfers best when the same restraint is applied at export size.
