I just remixed katakanakana's game and made it english, so english players can play the game without not knowing what is going on. When you play against the computer, you start with the attacker. Place the cursor on the ball and click at the right time to hit it. If you shake it early, it will pull. The closer you hit the ball to the center of the cursor, the better the hit will be. I can't bunt yet. When pitching, use the arrow keys to determine where you want to throw. The better the pitcher has control, the more the pitch will be on target. It will be easier to go. After deciding the course to throw, press the E key. You can see the types of pitches you have, so select the type of pitch from the list using the number keys or Z (back 1), X (forward 1), and C (set to 0). You can pitch by pressing the space bar at the end. If you don't want people to know where you're throwing, you can hide the pitch cursor by holding down the L key.
Credit to katakanakana for making the game, I just changed it a bit
