Oh, believe me, you've just gotten started. This game will have you crawling all over it to find the various secrets.
As far as I can tell, it isn't possible to double-jump in Knytt Underground without the powerup, either as Mi, Bob, or a combination of the two.
If you want to keep your balance while bouncing on an angle, just push against the direction you are being bounced.
In the Disorder, there are four pedestals that you place the objects on. Doing so will give you access to an extremely rare item.
There is a map of the Disorder in game, but it is hidden away in a secret chamber.
