I like the use of gray tones. It makes the hospital seem really creepy. The game froze during one conversation, otherwise I experienced no major problems. I cannot say too much about the story without spoiling, but it was fun to investigate and trick my way through the game. The 3d works well enough, but for me it just adds the trouble of where to click to make my character walk. I'm a story first kind of guy, but I guess 3d may help for immersion, especially for younger players.
And...interesting use of the jam theme!
