NameError: name 'Actor' is not defined

Hi - sorry feel like a real newbe here. Installed pgzero (and pygame) successfully, then ran the code, but had this error:

Traceback (most recent call last):
  File "C:\Users\fred\PyProgs\Wireframe\Wireframe14 - Donkey Kong-style walk cycle\Wireframe-14-master\walkcycle.py", line 2, in <module>
    class Player(Actor):
NameError: name 'Actor' is not defined

Was going to try to do this with a small code club I run... :-(

Run pgzrun walkcycle.py.
