Pastel Japanese Mobile Game Store Screenshot

A polished Japanese mobile game promotional graphic in a soft pastel kawaii style, formatted as a square split-screen advertisement with 2 vertical panels side by side. The left half has a pale blush pink watercolor background, and the right half has a warm cream-to-pink gradient background. At the top of the left panel, place a large bold rounded Japanese headline in dark rose pink reading {left_headline_text}, with a smaller gray subtitle below reading {left_subtitle_text}. Centered below is a black-framed modern smartphone mockup showing the title screen of a cute pastel escape game: a fluffy cream-colored kitten with big watery eyes on a sparkly pink background, decorative bubbles and hearts, a logo in Japanese reading もふもふミルク にゃんこ with a smaller ribbon-like subtitle 脱出ゲーム, and a large rounded start button near the bottom reading はじめる. Around the phone on the pink background, scatter translucent soap bubbles, tiny bows, hearts, and star-shaped sparkles near the lower area. In the right panel, place a large bold rounded Japanese headline in dark rose pink reading {right_headline_text}, with a smaller gray subtitle below reading {right_subtitle_text}. Centered below is a second black-framed smartphone mockup showing in-game play: a dreamy pastel pink room with striped wallpaper, a wooden shelf unit or vanity table, 3 small plush animals lined up on the top shelf, 3 empty square frames or slots on the middle shelf, and 2 small objects on the lower shelf including a pink rectangular item and an angled card-like object. Add a tiny top-left room title inside the phone UI reading ミルクのおへや, a small circular icon at top right, a vertical lock icon on the right edge, and a pale bottom text bar reading アイテムがまだないよ. The entire composition should feel like an App Store screenshot for a gentle puzzle game, with soft lighting, pastel pinks and creams, rounded typography, clean spacing, and a cute feminine aesthetic.
