Martin has a youtube channel called KrimsonRogue where he reviews books and movies and stuff like that. It's a good channel. I recommend it. In one of his videos, Martin says that Micro God is not the best because he left a few typos in, little stuff like that, and sure, there are some writing mistakes here and there. But the reason Micro God is good is that Martin takes a plotline that would normally be considered dull and uninteresting, and he makes it interesting and enjoyable. On the off-chance that Martin himself is reading this. Good job. You did great with this book.
Note: there isn't a sequel, at least to my knowledge, but if there would be one, I'd have high hopes for it.
