Ok, so, apparently it was set as easy without me noticing it, I thought they died a little too easy but now I have played a while and don't want to start all over.
Is there a way to set the difficulty without starting a new game ?
Ok, I see now, "start new game" lets me pickup at the current chapter so I guess that's no too bad, at least I don't have to start over from the beginning.
Hmm, weird. I played on Easy for the first 4 chapters then switched to normal on the fly and it worked -- I played on Normal the rest of the way through.
