I was actually going to mention that after completing it last night for the first time, that I found the overall game quite easy, so it's not just me then? I was playing it on normal, but I don't recall feeling once challenged. I also never died once, and I certainly wouldn't call myself a skilled gamer.
Having around 80 medipacks at all times certainly helped.
Is Route B harder? Probably going to start that this week.
No it's quite easy to be honest, but you still need to pay attention in the bossfights, the optionals are way more difficult if tackled 20-30 levels below, though nothing approaching dark souls difficulty.
