The Challenge
Delivering console-quality feel in a React Native game
- —Games demand consistent 60fps — any frame drop breaks immersion and hurts retention.
- —Complex particle effects and animations couldn't rely on standard RN components.
Product Goals
- ✓Maintain 60fps during gameplay on mid-range devices
- ✓Build engaging retention loops without compromising performance
- ✓Ship to both stores with in-app purchase support
The Solution
Skia-powered rendering with performance-first game loop
- —Used React Native Skia for GPU-accelerated rendering of game elements
- —Implemented Reanimated worklets for physics calculations off the JS thread
- —Built session analytics to optimize retention mechanics based on real data
Architecture
- ✓Skia Canvas for game rendering
- ✓Reanimated 3 worklets for physics
- ✓Hermes engine optimization
- ✓In-app purchase integration
