I have no idea whether or not this has been said before ( a search revealed nothing)but here it is: Spoiler: Warning: Will blow your mind (click to show/hide)With Num lock off, press and hold down End on the numpad. A whole bunch of squares will float on the screen. The glowing square shows your location. Half-squares mean there is one tileset (the colours dictate tilesets) and whole squares are two tilesets. A small cube in the corner means 3 tilesets. This is all a bit confusing, but try it out. Yes, it is a map of the knytt world!
hmm, if I recall correctly, those squares didn't have anything to do with tilesets. That thing was the ambience system, and the colours represent different melodies & ambience noise. At least the game doesn't use tilesets (in the same way as Knytt Stories). But it might also be that Nifflas used those large squares fr the tilesets just to remind him where some part of the world ends and where some other begins.
