Okay found another issue. When talking to Charlie in the Berry Forrest, you can't see the upgrade icon [S]. It gets cut off out of frame. Putting it to the right instead might be the better choice at least for that area.
One more thing... when finishing a mini game that increases horniness, the sound still plays at full volume regardless of if it is lowered or completely mute through the settings. Same with the sound of the letters Charlie gives.
An additional error where Nico is speaking but instead it should be Kira when talking to her casually. "Keep giving me a taste of that meat stick" and "..." have swapped places for some reason.
