Rock, Paper, Scissors game solution using Sass, Flexbox, Parcel, BEM

Hi, I just finished a Rock, Paper, Scissors game and therefore have a few questions. I am currently working on making my code more readable and clean, so I would be very grateful if someone would rate my project in that regard. Besides, I have a few more questions:

Are there bad code practices? Have you noticed any mistakes I haven’t seen? What else can be improved in the code?
