The game isn't bad, but it also isn't...great.  The writing is all right, but in regards to the main boys routes, the romance scenes are cookie cutter, the writing is reused with name changes for the most part.  The plot itself for each boy also plays out very much the same for each of them with small changes here and there, you can think it akin to the version differences in a Pokemon game.  I would honestly just recommend only really playing one of the main routes of a boy that you think you will like and then doing the side characters routes who are actually all unique and in my opinion, more interesting.  The voice acting is also quite good, I think that is one of the stronger suits of this game as well, some of these voice actors have all also since being in this game moved onto having roles in bigger games or in anime projects, so there's definitely great talent here.   As for the art...it's all right as well, it's certainly not art I would call my favorite, but it's fine enough, especially for a free game and this is purely just my preference, others may really like the art and that's valid!  All in all, it's a fine enough experience especially for free, but I honestly wouldn't ever spend money on it, just personally.  If you've got some time to burn though it's certainly not a bad way to spend it.  But if you are really looking for a great experience and are short on time, you can certainly find something better elsewhere.
