You are probably using the 'isKeyDown' method instead of the 'getKey' method. As long as the key is down, the method will be run repeatedly with 'isKeyDown' because many cycles pass between the time the key is pressed and the time it is released. The 'getKey' method will return a value at the moment a key that is pressed is released. There are two ways to deal with the issue. (1) add a boolean field to the class called 'spaceDown' and when 'isKeyDown' becomes true while 'spaceDown' is false, set 'spaceDown' to true and run the animation; when the 'isKeyDown' becomes false while 'spaceDown' is true, set 'spaceDown' back to false. 
// add instance field
private boolean spaceDown;
// is act or method it calls
if(!spaceDown && Greenfoot.isKeyDown("space"))
{
    spaceDown=true;
    animate();
}
if(spaceDown && !Greenfoot.isKeyDown("space")) spaceDown=false;
or (2) use 'getKey()'. First be aware that once a keystroke is returned with this method, that keystroke cannot be retrieved by way of the method again. Therefore, it is best to set a local field to the value returned. 
String key=Greenfoot.getKey();
if("space".equals(key)) animate();
The code is simple, however, has drawbacks; first, if you are checking for keys using 'getKey' elsewhere, it may not run right; and, the action will always occur when the key is released instead of when the key is pressed which would usually give a better 'feel' to the game.

Actually, the animation looks pretty good. The only improvement might be to not have zelda looking right immediately after stopping while going left. Easy fix: in the 'nomal' class code, in the 'if' block that checks that none of the five keys are pressed, after setting the image (line 75), add the following line: 
if(dir == -1) mirror();
If you believe that it is not quite what you want, explain clearly and I will try to help. Same with any other issues you may have. BTW, good job so far; and the music goes well with it.
