According to virustotal this is also flagged as malicious, although it's 1 flagged against 97 positive. Anyway, one has to be cautious how they access the site. I just tried the demo earlier before checking, didn't think much of it since I didn't plan to sign up or visit it again, rather just to understand the essence of the game.
Could it be a false positive? I checked it on Virustotal just to be sure, and it shows 0/97
