Just finished playing through this, and oh my, this was an emotional rollercoaster. I liked how the mood shifted throughout the story - good job building up the confusion and then resolving it at the very end. It's a difficult topic that you chose there, but I think you handled it really well.
I also liked the way you integrated the cell phone with the menu, blurring the borders between the game's interface and the story world.
Great work overall, very intriguing!
