Hanabi Heart
Hanabi Heart is a touch-only mobile firework studio set at a Japanese summer festival riverside. Draw any doodle on the night sky, then tap to launch it skyward, where it explodes into a firework whose sparks trace your exact drawing before gravity pulls the glowing ember lines back down. Each stroke is resampled into thousands of embers with drag and gravity, while smoke ghosts linger for a long-exposure feel. Draw again to layer a full show, and the finale replays every burst together. When you finish, you get a long-exposure card of your firework show that you can share to the community or replay instantly. Built-in English and Chinese locales round out the experience.
