What could 1 person do against many ? Looks just like a normal case of spammer. Just make sure a lot of people rated your game, and you don't have to worry about him.
I guess you removed his name on purpose, right?
Also it's better to report him, so he gets disqualified and can't rate more games.
Oh hey they left a comment on my game too. I mean, for mine some of they aren't wrong but this is my first time even trying to simulate AI and lengthen a game. It was really discouraging for like five minutes but then I read all the other constructive criticism and it just encourages me now.
I like constructive criticism, it's helpfull and makes you feel "Yeah, I did great but I can do even better!" , but if you just say it's bad and be mean, that sucks and if discourages people.
My theory is that these types of critics purposely make the bad side of ppls games known for their own game to stand out as perfect, which is pathetic.
