Python Hangman (guess the word) game

Question

I implemented a Hangman/guess the word clone in Python. This is my first attempt at making an actual interactive app instead of just a list of functions or a static program. It is also the first time I try to actually implement classes since I've been having a hard time wrapping my head around them. It's probably not the best or most practical application for a class, but it saved me the trouble of having to go around declaring globals and nonlocals throughout the code.

import json
import random
from os import system, name
import msvcrt
import colorama


class Hangman:
    def __init__(self):
        self.level = ""
        self.word = ""
        self.wrong_chars = []
        self.from_victory = 0
        self.from_defeat = 0
        self.game_state = ""
        self.on_repeat = True

    @staticmethod
    def cls():
        system('cls' if name == 'nt' else 'clear')

    def difficulty_scene(self):
        print("""
  DIFFICULTY LEVEL:

  Very long words (10+ characters) and 10 lives

  (2) Easy.
  Long words (8 or 9 characters) and 8 lives

  (3) Standard.
  Medium words (6 or 7 characters) and 6 lives

  (4) Hard.
  Short words (4 or 5 characters) and 4 lives

  (5) Impossible.
  Tiny words (3 characters) and 3 lives.

if __name__ == '__main__':

    with open("words.json", "r") as read_file:

    game.main()

words.json is a 2-dimensional array of words sorted by length.
