Capacitor is a great platform for building cross-platform games. With broad support for WebGL and canvas rendering, developers can build high-performance game experiences on modern mobile devices.
We generally recommend building with a game engine, which will provide primitives for common game objects and features, though developers are free to build from scratch.
Phaser + Capacitor
To get started building games with Capacitor and Phaser, see the Capacitor + Phaser Starter template, which includes consideration for mobile device scaling and defaulting to landscape mode.
