It stays true to its origins as an ero-game, with incredibly moe girls each getting a bit of face- and body-time with the hero, and some quite erotic (but censored) nudity.

The plot, such as it is, is just there to throw the protagonist together with one or other of the girls. But the character design and candy-floss coloring, coupled with some very moe voices, make this about as good an analog of an ero-game as broadcast TV will allow.
The voices are key. They are not all top anime voices -- but they are ero-game voices. The same people do the anime as did the original game. In the page itself, I give the pseudonyms they used for the game. Details in notes on the page.
If you're wondering what the second good game adaptation is, that's Amagami SS, which adapts an all-ages dating game in a new way. It gives four episodes each to six girls, so that each route of the game gets a full story, and the protagonist develops a full relationship with each girl.
