Use the mouse pointer to aim the arrow, and press the space bar to shoot baseballs at the bats. If a bat touches the far end, then it's game over!
The finished game! Adds some more complicated sound and visual effects, as well as smoother vanishing mechanics (baseballs disappear after they hit a bat). Remix ideas: Different sprites, sounds, or backgrounds. More levels. Have the enemy sprites go faster or appear more often. Make the enemy sprites bigger or smaller. Add different enemies that are worth a different amount of points.
