How to play
Tennis is a 2D sports game about playing a prolonged tennis match against one opponent with the mouse or keyboard. To move your players, hold the Left Mouse Button and drag the cursor left/right or use the A/S keys. Your tennis player will automatically hit the ball back over the net when they're in range. The goal is to keep hitting the ball back to your opponent to keep the volley going for as long as possible. Whenever the ball makes it past your player, the volley will end and you'll have to start over from zero.
You don't get a lot of options in terms of cosmetics and game elements, you just have the court and your lone opponent to hold your attention. When you start playing, your opponent will serve the ball and you'll need to move into position to receive it. As long as the ball is going toward your racket, you'll be able to hit it back. The opponent will always be ready to receive the ball so you'll be moving to respond. If you miss the ball, the game ends and you're left with the maximum number of volleys you were able to reach.
