I haven't played this game and this guy sounds a bit too personal in his criticism. That said, it does sound like a bunch of valid points that nobody has rebutted.
It's a spoiler bro he didn't even bother typing a "spoiler alert" before commenting, that's why you should play the game first before reading the comments, and he's just hating. The dev give he's blood and sweat to make this game, and I know we have our own opinion, but if it's just pure hate you should just keep it to yourself.
Funny that he pointed out a lot of well thought and valid objections and your response is "he's just hating."
Probably easier for you to do that than to actually read or understand them. Maybe if you did you could actually have something of substance to rebute them with rather than an emotional outburst.
