My 3rd game developed with Godot 4

I continue my learning journey with Godot 4 by developing different kind of games. 

This one (the 3rd) is a "volley pong" which brings different challenges.  

I decided to develop the ball and the paddles (hands) as RigidBody2D to play (and lean) with Godot Physics. 

I try to have a very well designed architecture, meaning having small, autonomous objects. So far, I'm happy with it. 

So far, the game is running with PVP and PVC (funny to see AI playing). 

I want to implement a collaborative mode, where both players score as long as the ball does not hit the ground. 

The game is still missing sounds, music and "colorful beach-style menu"
