Tonight, who will elope with whom?

Develop an interactive narrative mobile application centered on a chaotic magical engagement party setting. The core cast consists of six distinct, fully realized characters, each with carefully crafted hidden backstories and undisclosed secrets that shape their interactions. Users select one of the six characters at the start, then progress through three distinct, lightly melodramatic story acts: a botched wedding vow exchange, a misdelivered love letter subplot, and a midnight elopement sequence. Design a dual tracking system where a heart rate meter and a chaos meter dynamically shift based on user choices, leading to three separate branching ending types that deliver either a uniquely tailored romantic conclusion or a whimsical chaotic payoff for each user’s playthrough. Implement full seamless bilingual support for both English and Chinese language toggling without disrupting in-game progress. Create all original visual assets in a retro Japanese anime cel-shaded art style, including full character portrait illustrations and hand-drawn 2D environmental backgrounds for every story scene. Ensure the entire application is fully optimized and compatible for smooth operation on the Eazo Mobile WebView platform, with consistent performance across common mobile device screen sizes and operating system versions. The experience is designed to prioritize immersive, choice-driven storytelling with a light, playful tone throughout all story beats and interactive elements.
