If you are just looking for a quick fap then this game isn't for you. It's a game about corruption of a pure and somewhat naive girl, and that is the main focus of the game. Having her go full slut within 5 minutes wouldn't make for a very interesting game with that premise. So yeah, it takes some time until the story starts to unfold.
If you don't like NTR then you should skip this game as well I guess. I mean you CAN go down the route where she stays true to her future hubby, but the game basically lives from her being led astray from that path.
Is it the best story ever written? Nah, but it serves its purpose well enough. For the most part it is consistent, and I've definitely come across way worse.
It's also refreshing to see a creator actually using handdrawn characters and not relying on the same 10 3d-models with minor adjustments like 80% of the games here. There's actual effort put in this game. I also dig the artstyle, but that is just personal preference.
But not all is rainbows and unicorns.
Traveling around the city can get tedious over time, especially when you keep traveling the same route again and again. I'd suggest to either implement a way for point-to-point quicktravel that actually deserves the moniker (the bus/subway system is IMHO still tedious, and you have to get there first) or to sprinkle in some random events.
There are multiple routes one can follow in the beginning, but at some point, dependent on how far you progress in each route, they become exclusive and you get railroaded into the development of that route. For me that is neither a pro nor a con, that's just the way the game is designed. However, finishing a specific route can also become somewhat tedious as you usually follow the same steps for the most part
1) Go to work/place (literally walk)
2) Do stuff
3) Go home
4) goto 1
A minor gripe I have is the world building. For whatever reason the world this takes place is ours except it isn't. The game clearly is meant to take place in LA, but it doesn't, its in "Freedom city" (I think). And the heroine is clearly meant to be japanese, but she isn't, she's from some made up country that sounds very japanese. I'm not sure why, but to me that makes no sense. As I said, a minor gripe, but I just find it silly.
The biggest issue I have, however, is that I don't think that this game really needes to be a RPGM-game. You could convert this into a Ren'py game with very little effort and without loosing anything except maybe that one minigame, but that is something I can live with. The map only stretches the game time, but it doesn't actually add anything relevant to the game.
But overall it's definitely one of the better games, and for all its shortcomings it kind of grew on me.
