I had many issues with iOS since their web view component didn’t enjoy full webgl accelleration. This made opening my game slow in chrome and slow when wrapped in a cordova app without using crosswalk, eventually just reduced graphic demands precalculating composed sprites, placing caps on concurrent bullets, reducing the game area etc.

In the end was running well enough from the browser too making wrapping moot.
