Tennis Physics is a classic style of retro game. Your task is to control the character hitting the ball. You can invite your friends to compete in a 2-player mode.
Tennis Physics is here to demonstrate exactly how wonderful 2 player tennis games online are, and of course, they would, since playing sports games with another actual person is always more enjoyable, even if we're talking about doing it electronically, which is the case right now.
To leap with your tennis players, use the W and Up keys, two for each player, using just one key if playing in 1P mode and facing off against the computer and utilizing the unique touch controls if you're on a mobile device.
The rules are simple: smash the balls with your players' rackets and make them strike the other side; if your opponent does not return the ball, you get a point. They'll try to do the same thing.
