A storybook for Children's Day! Can the littlest red koinobori climb a waterfall and become a dragon? Kids Mode lets children reach the dragon ending even if they fall.
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
