• I checked the current issues for duplicate features.

🤔 Is your proposal related to a problem?

So far we can only mute / unmute and adjust with a slide bar the sound of the home screen but not the sound when we play the game.

😍 Describe the solution you'd like

• Be able to mute / unmute
• Adjust the sound with a slide bar

👍️ Describe alternatives you've considered

• When we press the key "ESC" to pause the game, it would be great to adjust the sound there.
  

✍ Additional context

Feel free to adjust as you want but try to do something that looks good for a great User Experience :)
