Baseline Bash

Baseline Bash is one of the Microgames in the Sports folder in WarioWare, Inc.: Mega Microgame$!

Gameplay
The screen is filled with a tennis court, with a tennis player on either side. The player controls the one closer to the screen. The computer player serves a ball, which must be returned with the "A" button when the ball turns red. In level one, the ball moves slowly, and is fairly easy to hit. However, in level two, the ball is lower and faster, and in level three, the ball is even lower and faster. Depending on the speed of the ball, the ball may have to be returned twice.

In the Grid, a minimum of 20 levels must be beaten to beat this Microgame.
