not sure what I was expecting, its just a game to have on in the background if that, the most you really need to do is just max out the points you get from each girl, you dont even need to click since you can let the game idle and it will give you points.
the last girl is a "boss" fight, which just involves clicking on her to break her shield then tear her clothing while clicking on the random block icons to stop her from hitting you, it's tedious since you cant let the 1 meter fill up and each time you tear a piece of her clothing she moves faster, the shield respawns faster, and the blocks happen more often, once you beat her the game is effectively done and there isnt anything left to do
