Ember Letters
Ember Letters is a touch-only, mobile-portrait fireworks canvas. Draw any doodle on the night sky and tap to launch it skyward, where it explodes into a firework whose sparks trace your exact drawing. Each stroke is resampled into thousands of embers that fall under gravity and drag, while smoke ghosts linger behind them. Draw again to layer multiple shots into a full show, then watch the finale replay everything at once. When you finish, the app composes a long-exposure card of your firework show that you can share to the community or replay instantly. Built-in English and Chinese locales, no login, no external services, and every control fully working end to end.
