The title revolves around hanabi, the Japanese art of fireworks: it lets you build combinations of powder, color, and shape to create pyrotechnic displays and then watch them burst on the DS screen, with a more contemplative than competitive tone.
It's an absolute niche piece of software, made for the Japanese market with no impact whatsoever outside it. Its appeal lies in the novelty of the concept rather than in offering a conventional playable challenge.
