Good demo. It looks like the dialogue and writing aren't bad, which is a big factor with how good these kinds of games are. I'm looking forward to seeing what the full game will look like. This might have been short, but it does exactly what a demo needs to do, which is introduce the important elements of the game. The conversation with family at breakfast hints at the story, and we get a look at the setting. It would be nice if it were a little more clear what is required for the medals... I got all of them on my first run through, and I'm not sure exactly what I did for them (no notifications or anything).
If the full game lives up to the standard set by this demo, it's going to be great. I'm looking forward to it.
