Same here, I tried Crosswalk for the first time. In my case, it was a little bit buggy but great. It works really smoothly and supports Clay.io perfectly
And yongsheng , here's a problem list.
1. My app is not that a big project. However, the size of APK file is almost 18mb, while CocoonJS version is about 10MB(10MB, that's also big size though.)
2. No Ads support(you know)
3. Audio is more buggy than I expected. It's too much delayed from the exact timing, and totally ignores volume settings.
4. When I open URL like "http://play.google.com/blabla", it opens "in the app(not on the default browser of the device)" as desktop version and I can't go back to my game.
