Overall: 2/5 - It seems like the developer started out with an idea and a good technical baseline, but then just rushed a game out-the-door. The only thing that's really good about this game is the fancy user interface. The UI is really well done, but it's almost completely wasted since there are hardly any gaming elements.
Story: 2/5 - Your father is missing and you're trying to find him, in the meantime, you're living with your stepmother and stepsister. The premise is not original, but it's fine for a porn game. Unfortunately, the execution of the story is terrible.
Writing: 1/5 - It's terrible. It feels like it was written by a pre-teen girl, and there are lots of spelling and grammar errors in the translation, too. Strangely, it starts out OK, but you only have to get a couple minutes into the game before it becomes painful to read.
Renders: 3/5 - The models are average. Most characters shown are sprites over sterile backgrounds. Lighting and reflections are poor.
Animations: 4/5 - The animations during sex scenes are just average. The idle animations are a nice touch, though. Things like characters breathing, the plants swaying with the wind, the fan turning, etc.
Content: 2/5 - You can play through the entire game in about 30 minutes if you actually read everything, which is unlikely. There's really not much content. You only get about 6 sex scenes in a playthrough. The quality of the sex scenes is poor, too. The women just seem to have sex with the MC for no reason and it's not erotic at all. Each sex scene has 3 animated positions where you have to frantically click to fill up a bar that gets you to the next position. Note that each scene shows that it has 4 positions, but positions 3 and 4 in almost every scene are the same with 4 being a faster animation of 3. It looks like 4 positions were planned, but the last one was never created because the game was rushed. The MC doesn't even finish in most of the scenes, which is telling.
Gameplay: 1/5 - It seems like it was designed to be a game, but the actual gaming elements were never implemented, except for a few choices and the pointless clicking during the sex scenes. The sandbox is 100% linear where you have to do everything in order. There's a notebook where you conduct your "investigation" into your father's disappearance. Players are never given any instructions on how to use the notebook, but it doesn't seem to have any impact, anyway. The choices impact what scenes you get, but you have to guess at what impact they actually will have. The game appears to be designed to be played multiple times to get different scenes and endings, but I doubt most players will bother.
Bugs: 5/5 - I didn't encounter any bugs, which is impressive given how much is going on in the user interface. Even the performance was fine which is usually a problem for games with animated user interfaces.
