First of all, the story is a bit derailed so to say, since I'm speaking from game to anime. In the game, you're actually the 3 heroines, Koharu, Mikoto and Nanami. The second part is this was based on a Visual Novel so you have the various routes, good and bad endings. Keep that in mind, because they can't cover all the male characters into the anime, so they've basically stuck to their main pairing for the anime. You won't notice this much in the anime as a standalone though.
Story, small minor changes happens so that the story line can be made, I might have said it was derailed but nonetheless, there is a story line, you just need to patch it here and there a lot in the game. The anime pretty much compact everything so it's a nutshell, less brain-work.
Art/animation, I have nothing to say, the only thing that might have tripped me off is how they decided to execute their "powers", the game showed it a bit differently but otherwise as a standalone factor, you wouldn't noticed that.
Sound, it was pretty similar to the game but of course, the anime has more time duration so there's more tracks. I think it suits the scenes so it gets my thumbs up. Either way, I'd say it's very pretty and touching. I think I'm being a bit prejudice but either way, as a standalone factor, it does work well.
[Update: Going through the entire anime soundtracks and not just relying on listening from the anime itself, it's very good, majestic and yet very pretty.]
Character, this was lowest part of all, in the game & anime, they made a very quick sum up for each of the characters except maybe some (in game) but the anime skipped this out. You really wouldn't get why the story happened until the end of the anime, and it's still pretty shady because of this. This also ties in with my "Story" rating factor, I wanted to give the story rating to a 7 but the characters did drag it down to a 6, for these reasons.
Koharu's part, they messed it up in the first episode. And in the end, Kakeru goes all Spider-man for her. I can go on with this and the way Ron just did that toss..., the physics were defied (game kept the physic logic intact). So this was a bad part of the anime. And the pairings were really bad, despite the main pairing, it mainly focused on Koharu and somewhat of Nanami, barely Mikoto. So much for 3 heroines in the anime, more like 2/3 (lol).
Enjoyment, I did enjoy it out of anticipating for the anime when I finished the game, but I did have quite the "wtf in a bad way" moments.
Overall...yes, long story short, if you've played the game, this might be a real trainwreck but, IT DID do a better job than the other otome anime adaptions, just better but not great. But gamers, let's keep this in mind, the visual novel WAS beyond the length of a simple one cour anime, so ease up on the full cannon materials here, it's not possible.
As a standalone anime, this is definitely watchable, if you haven't played the game, it's definitely passable, you won't really have a struggle at all.
I stand by what I've said and my overall is definitely a 7, with my review as a combination of the game and the anime, and somewhat prejudice view.
