Yes I was able to find all the hidden skills save for Zero G Buster, but that was more due to me not really paying attention on my way through that particular map. I mean it's in plain sight after all. I'd have to say that the hardest skill to get would be Bouncer Drive. The rest are found in a fairly stereotypical rpg manner. That is to say, they're just laying around waiting for you to stumble across them. In fact, I'm not entirely sure if I'd count some of those skills as hidden at all.
Anyway it was no problem. Like I said, I loved Silent Insanity.
