Man, this game would be really good if they don't make the sex scene comic book look alike which you need to push play button for each transition for each image inside a panel. despite the good art, it wasted on this mechanic, not to mention there is no dialogue/animation for the sex scene while they can do live2d for the talk/undress battle.
Regarding the mini game itself, i would say it pretty decent despite some minor problem, challenging but not impossible. For undress battle, i really don't understand this part beside only for you to look nude version of the girl, pretty boring i would say. and like anyone else said here, translation is your average MTL, understandable, but soulless.
