React Native 2D game engine built on Skia* and Expo:

• react-native
• expo
• react-native-skia: for graphics
• react-native-reanimated: for animations
• react-native-gesture-handler: for gesture input
• expo-av: for sound

*There is an old branch old-expo-2d-context that uses expo-2d-context/expo-gl instead of Skia.

• Graphics: SVG (inline and file-based) and bitmaps.
• Sound: useSound hook to play MP3’s.
• Math for collisions and vectors.
• Declarative, component-based programming paradigm with functional components.
