Many people keep saying they can do better, but where is your game? Where is your art? This is undoubtedly top 20 h game of all time. This is the pinnacle. If there are supposedly so many people that can do better - how come that's not reflected in the h game selection? The funding is there for people that can reach this level of work or come close to it. The fact is that people talk alot of shit, but can't back it up.
I don't see many here criticize the art, in fact the general opinion seems to be that Sunset's art is top notch and that's why over three thousand people are subscribed to his Patreon.
The complaints generally leveled at Sunset in this thread are that the code is bad, that he should hire a programmer to help improve it, and that updates are constantly postponed.
You're right that the world is full of people who talk a lot, and that Sunset has created a successful game project filled with tons of content. But comparing us to Sunset is a moot point since none of us have the artistic talent he has. We can only discuss how we would have run the project if we were in his position and had his skills.
By being a notable person creating something that's enjoyed by many, he has set himself up to being constantly second-guessed - that's part of the job.
