correct rotation

I'm making a game in which the player controls a rocket using the mouse, when you Left click the rocket "blows" away from the cursor in opposite direction. I've got the movement done but I can't make it rotate properly, it should be facing the direction it's moving. I've tried setting the angle of the ship using tan inverse(atan) of yspeed/xspeed but the rotation still isn't proper , can somebody help??

Here is a pic to help you understand better

No need for math, do this:

+ System: Always (every tick)
-> Sprite: Set angle to Sprite[CustomMovement].Angle
