Are all 3 endings available in this version? Can't seem to get points for Lily above 9, is that how you get the 3rd ending?
All three endings (2 bad, 1 good) are available. The good ending also has a minor variant version. Not sure what hints might help that wouldn't be very spoilery. Which ending you get depends a lot on your conversation in bed with Lily and how you handle the final lewd scene, especially how you finish.
