Assuming the same tone and style, but avoiding repetition, we could rephrase it as:

In just 90 seconds, you can win the match by scoring points with your head! Here's how to play: Move your player using either arrow keys or AD. Jump by hitting Space or up arrow key.
Aim to score points and emerge victorious within a 90-second span by striking the ball with your head! Here's how you begin playing: Utilize the arrow keys or AD to maneuver your player, while leaping can be accomplished using the space bar or upward arrow key.
