Currently the scenes are touching her at night (this includes jerking off on her), the Nirnroot scene is just teasing for now (will have variants later depending on stats) and lastly a "Quest" which just requires stacking Courage and entering the Living Room when you have enough.
The grind isn't so bad. And I hear 0.2.1 improves on that even more with a daytime minigame (which also has 2 new scenes I think).
What the dev plans for next update is improving the minigame added in 0.2.1 and more night scenes. He plans to release it in 1 week. That's about all that is known.
