It is a very good demo. I liked the twist how, after the apartment, you get to choose which of the 4 simultaneous scenes you get to continue on. My complaint there is that once I choose a path, I can't go pause and go back. (I eventually got past the part I was having trouble on, but I still would've liked to have been able to switch scenes.)
The death scene is sort of interesting. I wonder if that rewinding is an effect of Resonance, or just The Powers That Be being generous. I also took advantage of the preview video for the scene by Juno. I'm not sure if I would have gotten through that section as easily if I hadn't seen it already.
