Hello, thank you for this report. There seems to be an issue with the naming, as it should automatically name everyone to "Player". The name you were assigned is part of Unity's auto name assignment, which I have yet to figure out why is happening. I used the same code as in my previous game for this, where this issue did not happen. I will look into fixing this for the next version. I will also increase the 12 character limit :) thank you
edit: the update released yesterday changed the limit to 20 characters, and the bug that it sometimes assigned a long random name should be fixed
