Hmm seems like an interesting premise for a series, though the voice acting isn't always the most empathetic. I'm thinking of the parachute scene in particular, and when the girl throws the rock and the man turns around... can't say his impression conveys fear in the best way possible! XD Looked almost comical. The animation overall's not bad though. A bit simple, but smooth and effectual, I think expressions and natural movement are the two things that need most work, the lack of detail seems to work well with the style. So far so good! Gets you interested in wanting to see more; learn what it's all really about.
