The Police is an interactive mobile game where children take on the role of police officers to solve mysteries. 

As Project Lead and Designer, I spearheaded the full product lifecycle from initial concept and visual design to asset integration and global launch. I managed the project timeline and ensured the seamless technical implementation of the design system.

NEW IP

Strategic Character Development

I developed a new lineup of "Pinkfong Friends" IP to expand our global reach. Based on user research, I strategically designed characters—including a Panda for the Chinese market and a Rabbit/Crocodile for the 3-6 age group—to ensure global product-market fit.

Intro Animation

Immersive Storytelling

To drive user engagement, I led the scriptwriting and storyboarding for the intro animation. By collaborating closely with animators, I translated the creative vision into a high-quality cinematic experience that maximized initial immersion.

Avatar System

Resource Efficiency & Scalability

I designed a modular avatar system to maximize production efficiency while ensuring variety. By creating interchangeable parts—such as faces, expressions, and outfits—I established a workflow that generates countless unique suspects with minimal resources, providing a fresh gameplay experience every time.

Clue-Based Deduction Loop

I developed a deductive game loop where players identify the culprit among randomly generated suspects. By filtering through clues provided by Pinkfong friends at each stage, children engage in age-appropriate logical reasoning, leading to a rewarding sense of achievement upon making the final arrest.

Results

Market Success

Despite being our first paid app project, the game was featured as "App of the Day" on the App Store upon launch. It successfully reached No. 1 in the Top Paid Games chart, demonstrating strong market resonance. This achievement validated my data-driven approach—from strategic IP development to efficient system design—as a key driver for commercial success in a competitive global market.
