You can change the music that is playing during the game by adding it to the folder sounds/right_music/.
For the game to run successfully, there must be at least something. Don't change the music in the folder sounds/
like amaizing.mp3 or challenges.mp3, or, if you do want to do that, don't change their names.
####Appearance:
You can also change the environment, the aliens or ship appearance, however, the game may not look as attractive as it
was before. So, if you change, don't change the names!
####Highscore
Your record is stored in the highscore.txt file. If you want, you can change it and put at least a million :)
###That's all. Enjoy!
