If selling cheats wasn't enough of a red flag for you, here's what you can expect from this game:
Your standard stat grinding experience. Which yes, of course, is the easiest gameplay loop you can create, and is used in countless porn games, but does not excuse it as anything but that - grinding for the sake of grinding.
And even though the idea of your stats preserving over numerous replays itself seems nice, in the end, it's just good old grinding, which is worsened by the second complaint I have...
Very few models (whose names, mind you, are also locked behind that sold cheat mode, very nice, just abuse them and not even mention them). And by the nature of this game being a loop, you'll be seeing the same scenes over and over and over again. Even if the grinding itself was less of a hassle, there is just not enough reward for putting up with it.
Frankly, this is just showing what the eroge development has devolved to in the recent years. Have I seen worse games? Without a doubt. Much, MUCH worse. But it still doesn't make this one a worthy experience.
Although props where its due, at the very least this game warns you beforehand about videos having sound and provides an option to turn it off. This is definitely something others neglect and is definitely worth mentioning.
