Hello,
I'm a game developer, and i have a question about customer game rate and comment. If I get a rate with comment of customer about my game on google play, I want to reply them, and attach the new game link download in this reply.
I wonder if I can do that?

If you know anythings about that, please tell me and give me an advice!
Thank you so much!
