How are the participants of the alpha test selected?

We will select participants based on the information that is provided during the application process. Unfortunately, we cannot specify what criteria we will look for in the application.
* Please note that we will not be selecting participants in the order that the applications were received.
So no, they can't share it with us. Best to just be patient and wait your turn.
