[quote:2c1oyr9x]Advantages
High performance: It is the fastest webview engine.
Light weight: Only 5MB of space.
Compatibility with old OS versions.

Disadvantages
DOM access is restricted.

If your game does not require DOM UI elements and you want it to be easily portable to other OS versions and light.
If you are using a canvas based game engine, such as Phaser, Pixi, PlayCanvas, Kiwi.js …
