Memory Game (Vanilla JS + SCSS)

After a somewhat longer break, I wanted to start again and took a heavy challenge as an incentive. The project was a lot of fun and I think I learned a lot. I think one or two bugs are still present that I need to fix😆 In the future I would like to implement/improve the following features:

• Refactor scss File Structure
• implements Tests Frameworks (Jest,Cypress)
• support audio Sounds (e.g finding correct/false pair,Game Ending sound)
• implement highscore with localStorage
• build View with React.js or Vue.js

Feel free to leave any feedback and help me improve my solution or make the code clean!
