# 1 Guesses 10 times in loop due to the 'Less than 10" statement. And the
# first guess was a freebie since the guesses variable wasn't declared

# 2 next_scene_name in the play() method is the variable that holds the return
# value from scene.enter()
# Every scene is passed to next_scene(), which returns a string scene name.
# next_scene ALSO returns that scene string name, which gets stored in
# next_scene name
# this string is used as the argument for next_scene, when it is run again
# essentially, next_scene inputs the current scene and outputs the next one
# all as strings

# 3 Added a line 'cheat' that will pass every scene

# 4 Added this and moved the play() method to the end of the document

# Finite state machines take external output. In this case, we use a string
# to tell the game engine to run one of those states (Scene subclasses) in the
# map object. The entry action is performed when entering the state with .enter()
# and the exit action is the string return
