I really enjoyed this game. There were some problems however. The game would frequently freeze up forcing me to reload the game and loose all of my progress since my last save point. Towards the end of the game I would have to save very frequently for fear of losing my progress which somewhat took away from the experience. Also, once I reached level 15 and got the "Unlock" skill nothing changed. I was unable to get any of the bonus scenes which was very disappointing. And there were some more minor glitches here and there as well that weren't as big of a deal.
Overall I liked the story which was much longer and more in depth that I originally expected. And the sex scenes were well done and enjoyable. I can see this becoming a very good game with some more work.
