I just set up a paid game and I still have 0 sales, but someone left me a 1 star rating with this message without even playing the game:

"Don't know how to make a game? Want to do something that everyone's done before? Make it a knock-off candy crush game! Generic, basic game with nothing to offer what so ever. It's got the model of a free game, but the cost of a mobile app."

The game is a novel like tetris attack, also furry related. The only ressemblance to candy crush is that it's a puzzle, this person without playing, would obviously not know, but felt like he should say something not only about the game, but also about my team. 

Anyway, you can leave ratings without playing a game? Like, you're in the mood to being a dick and there is no consequences?  I can't even reply his rating?
