Memories lost to the ocean. Conviction etched in the heart. You wake up at sea with a blank mind. Fate hands you a second-hand shop, "Old Sydney Paper," and a manufacturer, "Third Feather." "Become the 'First,' and we leave together." Guided by this single vow from a one-winged girl, you step into the corrupt and dazzling Dark Heron City... Build grid-based production lines to hand-craft "Gene Tiles." Customize your shop and office decor—your style directly dictates your clientele and employee growth. Exploit emotions with rumors to manipulate the market. When you hold the fatal "Heart Info," will you expose it to crash the price to zero, or bury it to win their trust? Enter "Natural Selection" duels. No Mahjong skill needed—just match tile patterns to attack. Turn your products into weapons to defeat and annex your rivals. A story of "■ & Rain," "Bug & ■," and "Flower & ■." In the eternal night of Dark Heron City, find the only remaining warmth.
