Good project.

But,

I don't understand the video tutorial you have posted.

What I can understand is the user needs to open his coin folder to replace the wallet for the license he has purchased. Then only he can play the game. At once he uses the license, the developer gets his share of payment. If the user don't purchase the license he can't play the game. Am I Right?

I'm downloading the test and client tool. I will pm you for the coins once I'm ready.
