Short Version:
Is good. Cute enough characters, good scenes. There's a bit of everything in here, though obviously skewed towards exhibitionism and also quite a bit of pissing. No scat. Less than 1 hour to get basically everything. Also has an "unlock all" button in the scene viewer, so if you really don't want to play...
Pros:
+Animated Animations. I know, right? A lot of games lacks animations and are more often than not, just static images. (The RPGM kind of games. Yes, I know there are still plenty out there, but...
+Decent variety of actions/poses. There's doggy, cowgirl, two BJs, lesb. kissing, cunnilingus, rimming, and anal. Also pissing. Obviously, quite a bit of exhibitionism.
+Plot is sort of funny/interesting. I never laughed but I did that... breath thing where you exhale. About that funny. Dunno what that exhale is called, just not even a chuckle's level.
Cons:
-It gets pretty repetitive. Both, gameplay and dialogue. You spend a lot of time just running around to find scenes, and the dialogue gets kind of boring after a while.
-Short. I beat the main game in an hour.
-A bit confusing. One of the scenes, you have to switch your party leader, which is kind of unique, and actually interesting. Not a gripe at all, bu for another one, at the end, finding the last "achievement" is a bit annoying. You have to 100% the game, with every dialogue and achievement to get the last scenes and achievement.
-In the gallery, you do not have total control. You can play a scene, but it will play out until it is finished. So if you are just checking them out, or some other reason... Sorry bud.
Neutral:
~Characters are subjective. I found the girls cute, but not exactly my fetish. Also the main girls eyes sort of bothered me in some scenes. As this is a highly subjective field, I try my best to keep it out of the end rating.
~The areas you explore are limited. There's enough variety, like a coffee shop, arcade, park, and back alley, but there are also places that are completely useless like the fast food store or convenience store, as you never get money or go into battle.
~Music is meh. It's just there. It won't drive you insane, nor does it make you feel anything in particular.
Overall:
I think it's a pretty good HENTAI game. If you're looking for something interesting with a lot of story, well... This isn't quite it. If you're looking for hentai, this will pretty much scratch your itch. A bit annoying, but overall, not bad at all. For the faps, just go into the smartphone and unlock all. I am not sure if it was worth playing through the whole game to see the scenes.
