I don't think it was just people making comments his way. I think he got death threats and threatened in other ways too.
But that is not what happened at all. Nergal was the golden child for a long time. People LOVED him. He was very transparent and kept everyone in the loop and were more than willing to keep throwing money at him. Then it went radio silent for close to 8 months. AZL and this game went completely silent. ScarlettAnn who was the artist on both projects said they had a falling out for whatever reason and did not know what happened to Nergal. Nergal after a while came back and said he had burnout and family issues, which again is understandable. He also said he had to take a real job on top of it and wanted to be more transparent again. What do you think happened? Radio silent again after a couple months. Which led him to rush AZL and this game. Not everything is as it seems on the surface. For a while he also kept his Patreon going he got a couple months from people and refunded a month or so but eventually shut it down which is far more than a lot of other creators do.
I don't think he would want to. Like I said he wanted a slower pace and he promised a ton of things with AZL and UD. Working on either game would just bring him into the limelight again and just never living up to his promises. I really think he is where he wants to be again. He took the reputation hit and is smaller like he wanted to be. I do think that finishing the projects he had and then cooling off (which was his original plan) would have been preferred. I think he would have gone insane if that really was what was going on (burnout/stress). From the people I talk to who are subscribed to Solarion the updates are not high quality but he lets them know he is alive and is at least working on things to decide to keep supporting. I mean Solarion is nearing it's 4th year development cycle.
I say this all the time when it came to Nergal. People cheered Nergal until he pulled the Wootch. People hardly complained when he had to push release dates even. Nergal's PR was unmatched. He would release monthly sometimes bi-monthly updates. Companies/devs dig themselves into a hole by overpromising and cutting communication. It is why on this site the big joke/meme is devs never completing games and milking Patreon/Subscribestar. You will always have a few people mad or thinking they are entitled to things. It is why I said Nergal had it all. He did everything right until he just... vanished. It would have been a different story if he vanished and pulled a Star Citizen and came back with finished product but that is not what happened here. He could have done what Nergal did best and kept people in the loop and I fully believe people would not have cared or lashed out nearly as bad.
