Heartreasure takes place in a storybook world of hand-drawn 2D illustrations. The independently developed title traverses differently themed planets, with every illustration carefully drawn with ballpoint pen for a warm, nostalgic feel.
The solo piano EP publications on vinyl record and cassette tape are available for purchase through the BOOTH website in Japan. The two included acoustic pieces are the gentle "Shooting Star," reminiscent of twinkling solar spheres, and the light and jazzy "Sunnyside." The performance by pianist Chie Shijo was carefully captured using rare open-reel tape instruments.
From the Steam product page:
A pen-drawn world reminiscent of the illustrations in children's literature, accompanied by music for guitar and other instruments ripe with nostalgia for an old hometown. This is the background where the Story, a story meant for someone, unfolds.Steam - Soundtrack Now on Sale
