Mad World Age of Darkness

I was quite happy about being able to test it out for myself, so I pressed "Play now" , which redirected me to the game page. I made an account for the game, chose a server, read about current state of the project, and only after that I was told that I can not participate unless I buy a key. NGL this is quite frustrating, because I was not told I could not participate before I tried to actually start playing.
