I believe the game can *only* create fake choices.
No, the choices are real, the corruption of the girls will change depending if you tap the button or not. I guess that you'll get the reward later in the game, with the girls being more or less prone to be lewd with you depending of this corruption.
But that also mean that what is fake is everything else since taping the button, or not, is the only choice you can make in this game. Basically speaking, it's closer to a kinetic novel, where you've to decide if you accept MC's clumsiness or not, than a Choose Your Own Adventure VN. And, at least from my point of view, this remove all the interest the device can have.
The idea isn't bad, but clearly badly exploited. The game can have been the usual CYOA, but with unchangeable choices at some crucial points. Then the fact to tap the button, or not, would have become interesting and extremely meaningful.
