I finally got around to playing this, and was also really impressed with how good it is. The writing is funny, the puzzles are well-balanced, and the interaction density is very satisfying. The graphics have a classic Sierra-esque style (with some Kyrandian influences), and although they are "simple", they are appealing, balancing cartoony and realistic really well.
What impressed me the most, though, was the coding of things like the UI (that little hotspot indicator gliding around was very fancy), and the 3D parallax. How did you do those side walls in the corridor? Raw-draw them yourself based on 3D calculations, or what?
[spoiler]I think I have too suspicious a mind. I knew something was up with that doctor even in the intro. Not quite sure what was really going on, but maybe you'll continue the story in another game?[/spoiler]
