I like your friends review style, subbed.
His main complaint has been my complaint - falling from ledges. Seems a bit inconsistent so far but I'm determined to find out how to do it properly without fail. I think it's something to do with the speed you're walking off has to be slow. And don't correct the direction with the analogue stick, let it do it by itself.
Otherwise it seems like he was rather impressed by the design and gameplay.
I don't agree that it should be super easy to platform like in AC and much prefer the way styx is doing it. But ledge detection seems too unfair or perhaps the controls for it need better explaining with how many people seem to be annoyed by it.
This was the thread I read about it too:
