It's a pixel scene viewer that is mostly straight to the point. There's some puzzles and time progression stuff, but for the most part you'll just be viewing scenes.
Hentai quality and quantity is great for the length of the game. I do wish the short-haired police girl had more scenes, but oh well. It's great and for a scene viewer this is the part that needed to be done well and they hit it out of the park.
There's not a lot of puzzles, but some of them (namely for the pregnant girl) are a bit too obfuscated. Like who the fuck is going to realize on his own that in order to get her one scene you need to fail one of the sections three times in a row?
There's no real story in terms of dialogue (excluding the intro), but the events the girls go through do link together within their own stories. To advance these stories, you need to get through the girl's single h-scene, then fast forward time by one day, then you can advance to the next scene. Now, for the blonde girl and office lady these stories make sense. It makes sense that the next day the girl would return and the sexual acts would progress. Hell, with the office lady you can visibly see a change in her sexual prowess. For the pregnant lady, the day-by-day progression is a bit of a stretch but it's not unbelievable. For the police lady, however, its not believable in the slightest. It doesn't make sense that over three days (or more, she has four scenes that require three fast forwards) she'd return to the scene of the crime, get caught by the same people, then get raped over and over. It's a bit silly, but whatever. Police girl is still best girl.
Yeah, there's not much else to say and I'm surprised I was able to talk about this game for as much as I did. If you like pixel art, give it a go.
