author should work more on navigation and settings. the dialog button somewhere at the bottom of the screen is not the best solution in my opinion. you get to the location and look in the corner to see if there is this button, because it is unclear whether there are such and such actions.
there are no audio-video settings, you can't turn off/down the volume.
there is a quest with ventilation in the shopping center, it is unclear why these climbing mazes. it seems that the author is trying to compensate for the lack of content with all sorts of puzzles and mazes, this is exactly what people expect from a porn game. while it's too wet, we'll wait some more
