One other thing (and this is just me being extremely picky) with scenarios like this it makes sense to have the speed at 100% since the faster the speed the smoother the movement. Just a small tip :)

My mistake - to avoid confusing people, the comment: //Get the value in radians and cast to an int shouldn't have the int cast bit in, that's not done until the last line. Not very awake today!

Hi :) The problem is in your getRotationToPoint method - it doesn't quite do what you want all the time. There's also a much shorter (and simpler) way of accomplishing it - there's a method in the Math class called atan2, and this returns the rotation based on the distance (in x and y values) from a certain point. So if you replace the method with something like this: //Get the distances to the mouse in x and y co-ordinates int dX = x - getX(); int dY = y - getY(); //Get the value in radians and cast to an int double rotation = Math.atan2(dY, dX); //Convert to degrees rotation = Math.toDegrees(rotation); //Need to cast the double to an int return (int)rotation; ..it should work as you want. The above can be condensed into a single line - I usually write it in 2 or 3 lines to avoid confusion, in this instance I've typed and commented the whole thing out fully so you can see what's going on.
