I have read it, and I absolutely love this wall-breaking knight. Thinking of it as a generic regression story is a mistake, as the story itself is peak. Yup, nothing much had happened that we can say about the progress in the world itself, but from a protagonist pov many things had happened. The comedy is gold-tier; the story uses the gags from the plot itself. The art is top-tier, too. Overall, a good read, it lightens the mood every time you read it. So if anyone is still thinking about it, just read it.
