I think he has his opinions and he is free to speak his opinions on the internet. People think if it is a criticism, if it is negative, it is bad, and it is not. the new generation wants to live in a bubble. This is why most of things nowadays aren't that great. He is free to give his opinion, but I did put facepalm on his comment because of the words he uses in it. He could criticize negatively the VN without being so offensive, then after offending someone's creation with the intention of hurt the creator, he is victmizing himself for receiving facepalms. I get a lot of facepalms because I speak my mind online and I also do the same in real life, But I try not to be offensive, and when I am offensive, I do know some people will get triggered and reply back.
If he wants to go that route, at least he has to man up and deal with the consequences. Other than that, he is free to speak his mind and say what he thinks about this VN.
I personally love this VN.
And I love Erika even if people say she has male features as they said above and they are afraid she has a penis. Since I am into futa content, I wouldn't mind that either.
