Ok but the question how I get a client?

Btw I have money to buy both games but I'm not a kid I have 13 years old the bad thing is that my parents don't allow me to buy 2 games since they don't trust in "internet stuff".

That's why I will buy both but the other I will buy it like in 2 months.

edit: I will buy blockland but with the client I can play the "non-alpha" too? if yes how I get a client?
