Insert a username and press the spacebar to start the game. You can start from any level you want through the
Level picker.
Use the arrow keys left (<-) and right (->) to move the paddle in order to avoid the ball from falling out.
For every time it does, you lose a life. In that case, the ball will stop. Press the spacebar again and the ball will
be at the initial position -center of the screen. Press the spacebar one last time and the game will be resumed.
Watch out! The ball has memory and it remembers the direction it had when it hit the bottom. It will continue
going up to the opposite direction!
If you change the level when the game has already started -i.e., the ball is running- the game will be restarted.
Your points will be reduced at 0 and your hearts fully restored.
This is not an easy-mode game. Value your hearts because they won't be restored at every level!
