I have been thinking how this one will be maintained efficiently. Personally, I want to unit test every game, but this is really hard because all the games are in the same repo. And so many refactors, I want to do also.

I have one suggestion, we keep this repo, but we just provide links to the games. Each game will be a separate repo. It's really hard to maintain when a repo contains several projects particularly when we want to release the games, each should be released separately.

Hoping there is a response. Thanks.

Comet y Field crean una alta interdependencia entre ellas y dificulta el mantenimiento del código. Si se necesita cambiar una funcionabilidad o agregar una nueva característica, podría ser necesario hacer cambio en las ambas clases

class GameElement {
    public void move(Player targetPlayer) {
        // Lógica de movimiento común
    }
}

class Player extends GameElement {
    // Atributos y operaciones específicos de los jugadores
}

class Ball extends GameElement {
    // Atributos y operaciones específicos de la pelota
}

class Comet {
    // Operaciones relacionadas con el cometa
}

class Field {
    private Player player1;
    private Player player2;
    private Ball ball;
    
    public void update(boolean p1, boolean p2) {
        // ...
        player2.move(player1);
        ball.move(player1);
        // ...
        player1.move(player2);
        ball.move(player2);
        // ...
    }
}

Al usar una base común que contiene las reglas generales, el código se vuelve más sencillo de entender, ya que no hay repetición de estas reglas en diferentes lugares. Esto hace que los cambios y mejoras futuras sean más fáciles y rápidos de hacer, ya que solo necesitas ajustar la base común y no todos los lugares que usan esas reglas.

If you bet and lose everything it still shows you have money.

I tried running Frogger and blackjack, and it's fine. However, what annoys me, it's like taking control other applications (in this case on linux, my terminal), prevent me from typing anything into it whenever the game on the run. Seems like, it's resetting the applications UI every seconds.

When a piece has the ability to rotate and it all the way to the right, you are unable to rotate that piece. The only way to do so is to move the piece over and rotate from there.
