The most significant change? The game's pay-per-play subscription fee has been reduced to €10 (call it: $13.50 and change) for 180 days of playtime. (Previously, €10 got you just 30 days of Love.)
You can check out a video demonstration of some of the game's new features (as well as a basic tutorial led by Eskil himself) after the jump. Just try to stop the video as soon as it's over, because as you might imagine, the YouTube suggestions for a video titled "Love Tutorial" are unspeakably weird.
