LPChip, your example makes absolutely no sense to me. Maybe because I have never even heard of whatever that game is.
In my experience with the cheat, I found that topic where someone said how to do the cheat and whatever, but it had been modified by a moderator to the extent that you couldn't tell what the cheat was.
Now, I played the Explore Challenge, and I absolutely hated that level. It was so boring, I'm sorry.
So I just sat in NiffChat for a few minutes and someone said what it was.
I don't really see why such a big deal is being made of this. I almost never use that cheat except when trial and error has failed at least several times to get me past some kind of challenge or in my own levels where I don't feel like going through a challenge I made again and again. Speaking of which, the cheat is useful when you're making your own levels and want to explore everything you've made so far.
What I'm talking about, by the way, is the teleporting thing. The invulnerability thing is completely useless to me for the most part.
On another note, it is basically like cheating in some other video game. Especially these days with access to the internet, it is rather easy to cheat in almost any game and almost every game purposely has cheating in it.
But, yes. Those video games do not really advertise their cheats and thus Knytt Stories does not need to either, but I don't think it needs to be hidden in one obscure and uninteresting level (I know you can just look in the world document whatever, but that doesn't really make it less silly).
