Im choosing 4, but lets call it 3.5 stars.
First, its obvious the author is not an English as a first language person. But, with that being said a decent job was done 65% of the story of making it make sense and sound "OK" in English. On the last 25% it feels like the author used google translate instead of an actual English speaking person to translate. Some of the stuff was just bad. But, it didnt kill the story.
I very rarely judge the models/graphics in my reviews which is what accounts for the 3.5/4 stars. Most of the faces looked distorted because they tried so hard to make extreme lip/eye/cheeks. It was hard to look at sometimes, to the point where I actually stopped looking at them half the time. But this was also because of some of the insane body shapes that took away from realism. When a manga girl can appear more realistic than a CG girl, you know you are doing something wrong.
Now, aside from that, the story was actually pretty decent. It wasnt award winning, and sometimes I got stuck in odd areas because I could not figure out what to do (lots and lots of searching this thread for answers, which I took a star off for, even with me using the walkthrough).
Also, the ending was not great, but having finished "Babysitter" right after this one, I can say the ending here was FAR superior, so I wont even talk much shit about that.
