Hi,
I played the demo and I like how it starts.
I have few things to suggest:
1) Chose your destiny - this is so cool, but it needs to not be repetitive (as you wrote later). I suggest as well that you use it on plot forks or important decisions, not pre-Game over ones.
2) I don't really like the no rollback idea that you have - you can still overcome it easy it(save when you feel the need to do), maybe you can offer 'hardcore' mode in which it's enabled.
3) I also think that Max's story has untapped potential.
I am interested to see the development
