About

Perfect for Children's Day! In Japan, families celebrate Children's Day on May 5 by flying koinobori, colorful carp streamers, with the wish that their children grow up strong. The streamers are linked to an old legend: a carp that swims all the way up a waterfall becomes a dragon. In this game, parents and children can play through that legend together. ■ A picture-book story On Children's Day, the littlest red koinobori flies off from a family's garden. It climbs a waterfall, rises above the clouds, reaches the night sky, and finally becomes a dragon. Full-screen illustrations tell the story, and you can skip it anytime. ■ Easy to play Tap to swim up. Swipe to dodge. That's it! ■ Normal Mode and Kids Mode - Normal Mode: dodge the blockers and climb. A real challenge! - Kids Mode: falling is OK, so even little children can reach the dragon ending ■ Stages - Stage 1: Waterfall - Stage 2: Above the Clouds - Stage 3: Night Sky (clear it to see the dragon ending) - Endless Climb: how high can you go? ■ More to enjoy - Build combos for a high score - 8 looks for your koinobori - 24 Star Cards to collect ■ For parents - Ads appear only as a banner at the bottom of the title screen, and sometimes as a full-screen ad after tapping "Play again" on the results screen. No ads appear during play. - Tap "Pause" to pause the game at any time. - Game records are saved only on this device. Each play takes 30 seconds to 2 minutes. Perfect for families around Children's Day!
