Jaggie, uneven speed with basic movement script.

Hi!

I'm making a little prototype of game with a top down perspective,

The problem is that the movement speed gets a bit uneven, it speeds up when moving on the diagonal. The script that controls the movement is practically identical to this one: http://docs.unity3d.com/ScriptReference/CharacterController.Move.html and I have no rotation of the player. Also I have been using a analogue controller with this and it works in the sense that I can control the speed but it seems like I can only move in 8 directions, no middle ground, anybody who can tell me why?

Kind regards /Daniel
