A couple of feedback points.
1. I found moving around to different places a little confusing at first. Sometimes you click on arrows and sometimes you click on doors or whatever. It's not always clear which way you want to go or which way the different places are and sometimes the changing camera positions / orientations add to the confusion IMO.
2. Like someone else said, it would be great to see which scenes you've played, which ones you haven't completed yet and also to be able to replay scenes (like the Nurse and the PE teacher).
But great H-Scenes.
