x2 makes the ball go twice as fast and the red square is a wall, blocking the ball Change Log: (January 30th, 2020: Made the x2 last less long when collected) (January 31st, 2020: Made the balls direction of bouncing more unique, slightly buffed the duration of how long the x2 will popup, and fixed a bug where it would always serve the bottom player first)
