The art is good but the story is abysmal. Reminds you that playing some Nukige can actually be more entertaining than reading "manga" like this, because it has good artwork and at least tries at the story.
Granted, these games are a lot more expensive to make and buy than a manga, thus create more incentives for the writer and drawer to work hard on it to prevail on the market, but the manga market is also several times bigger than the eroge market, which led to several closures of even bigger software companies over the past decade, whilst the manga industry still seems to be relatively healthy (publishing a failure can be compensated more easily due to the low risk of the buyer of the magazine/internet chapters, so the chance of being abandoned over this is also low[idea of pocket change economy]).
