I don't know if the order is randomised, but the difficulty was all over the place. The first level I got was really big and difficult (sort of a labyrinth), while the second one was small and easy (one with the sword). A gave up in the third one (with the boat), it was just too frustrating with the camera movement and the boat movement. Jumping on angled surface also doesn't work very well. Though, I do really like the overall esthetics of the game.
