It's weird I have 2 ppls in my friends list but I can't see them in Ninja Records.
Have you been playing the game while being signed on the PSN HideoK and FadeToOne ?
On the positive side my skills have improved enough to the point where I don't die so much in mentor anymore. Up to chapter 14 and I hope to finish Path of the Mentor toonight.
Master Ninja is still going to be hard though as there are quite a few bosses where I bullied my way through with healing items and haven't found a good enough strategy that will prevent me to get hit...
Path of the Mentor feels like it's the right fun difficulty now though, challenging but not crazy impossible...
