Some more feedback to the player would be helpful. What are people liking or not liking? What determines if people like things? Is there a win condition? The game doesn't really make that clear. I think the best strategy (in the demo) is to click the dildo and slowly alternate between love and hard, but I really can't tell with any confidence if that's working or not.
Edit: Now playing the paid version of the game, I see that there is an explicitly stated win condition. Maybe I just missed that earlier.
