While this is among my favorite games on the site, it isn't without its flaws.
Since it is using TyranoBuilder, the performance is abysmal. Some how this game that basically just displays images and takes UI based button presses as input manages to crash my system within 20 minutes or so of starting it up. Keep in mind a lot of games crash my crappy old system these days, but mostly intensive 3D games and an annoyingly large subset of Unity based games. I never run into that with say Ren'Py, which this could have easily been made with instead.
The gameplay itself is a bit limited and repetitive as well. There are only a very small number of things you can do in this game, and you will be doing them over and over again ad nauseum. The sex scenes get boring after a couple of revisits, but since there are so few of them, you will be doing them entirely too many times on your way towards filling up her wardrobe.
The story is very sweet, but all too linear. You really have very little freedom in how things can play out. She either dies in the first couple of weeks or she makes it and you are stuck on the slow burn romance path. The only way to really get any variation out of this is to either get her nice and horny and then blue ball the poor girl for weeks until she can't take it any more, get her drunk, or start messing around with drugs (which basically just allows you to prolong the sex scenes you are almost certainly already tired of by the time you can unlock that feature).
With the negatives out of the way, let's finish off with the positives. The art is very well done; I've always really liked this dev's style. The music is alright, (but TB does a terrible job of looping it seamlessly). The story really pulls at your heart strings and makes you feel for Sylvie. There is seriously something wrong with you if you can play through this and not fall for her.
If you are looking for a heartwarming casual time waster to load up every now and then for a quick session, this is a great game for that. If you were hoping for something really engrossing with a lot of story options and replayability, then you might want to look elsewhere. This is basically a dress up game with some mild sim elements tacked on for good measure, as long as you understand that upfront and are fine with it, this can be a very enjoyable gaming experience.
