Basically, you are saying that different opinion equals to "getting mad"? I don't get it.
Whoever wrote the comment might have done some over the line with "creativity" thing, but it's their opinion. They are not saying the game is bad, neither did I if you meant me in "People might get mad". I think we should all relax and stop blaming others or making them a "bad" guy. Some people like originality, some people like making games that are similar to the big hits, like you meantioned "FNAF", but it's not right to call someone "mad" over their opinion and judgemnt, especially if it is non toxic.
FYI, toxic is when someone uses really really bad language and has no meaning behind it, otherwise no reasoning.
