FlappyBird Clone [First Game, Feedback]

Hi guys, how are you?

At last, I was encouraged and started to develop my first game. I gave Unity an opportunity, and I liked it.
For learning purpose, I decided to make a clone of an existing game.
I chose FlappyBird because I have enough notion of the mechanics and simplicity of it.
I would like to ask for a code review and get feedback on what aspects it can be improved, both code and good practice in Unity.

If you guys can help me fix the clipping that I have with the ground would be awesome.

On the other hand, I do not know if I did well with the implementation of the score panel and with the implementation of the sound manager. I would like to hear feedback about that too

I uploaded the project to Github. I leave the URL

Feel free to clone it and try it
regards

Bump
