Hi olkina
You could have good performance if your game is simple and maybe need to use cocoon.io for the extra fps in a bit more complex or bigger games.
Here are some of my games (all are using crosswalks(10-12) except Bobo World which is using cocoon.io)

I only tested with Galaxy S3. Somehow Crosswalks 14 performance are not great on my phone. So I just use Crosswalks12.
You may want to use Cranberrygame plugins for ads and etc. Also admob banner might also eat some fps. There are more tips at the forum for performance and etc. So good luck!
