Sleep Sex! The Girl From Gensokyo ~A Girl Even Ghosts Fear~

The wariness meter and affection meter are the two main elements of this game.
Interactions with Satori raise the wariness meter, which gradually drops back down again over time.
Once a certain wariness level is reached, Satori will wake up and the game will be over.
But if your affection meter stays higher than the wariness meter, even if she wakes up, the game will continue, and you'll be able to enjoy even more erotic scenes.
In this game, it is important to strike a good balance between the two meters. Get intimate with her through your interactions, but avoid raising her wariness.
By maintaining a balance between affection and wariness, you can progress through the game and experience a variety of erotic scenes.

You can freely strip off Satori's clothes in this game.
You can use your mouse to undress her as you please--but of course, if you make bold moves, you might wake her!
It requires delicate handling and a careful approach.
To raise your affection meter, use the right timing and technique to remove her clothes. However, if you raise the wariness meter, this can cause a negative reaction.
