Logic Bricks: Constraints 'Snap'

Hi,

Since I’m no coder, logic bricks are the first go to solution.

I used different constraints/methods, on a ‘character’ to try and keep it
stuck to other objects. But when moving fast around corners the constraints snap loose.
And so floats away the character.

I tried sharp vs rounded corners. But when the character speeds up it brakes loose,
no matter how round.

In short, I need Super Mario Galaxy gameplay, but quicker. Preferably setup with logic bricks.

Blender Rocks!
