During some weeks before the opening of our Discord we invited almost 15 close friends to test our project on Wax's Testnet. They're from diversified jobs and careers like programmers, designers, freelancers, etc.
The reason for us to decide for this Beta Test system is because we care about the security of our project. For example, if we opened Beta Test for everyone, a suspicious user could have found an exploit which they could have kept for themselves. This could lead to them exploiting the game after game launch as they could be using it for their own gain, harming the project in the process.
We get many requests about our beta test so we decided to open it for our community to find major bugs, visual improvements and things like that. You can participate it doing our Tutorial on Open Beta topic.
