Fight with the time and the changing direction to score the goal or save the goal to move on to the next level. With every level, the direction change gets faster so it gets harder to calculate the right direction to score or save. With every 10 levels, the target score and the background change, as well as the new time limit. After level 30, the time remaining after the goal or save is added to the next level along with the level's base time, except levels 40 and 50.
Every goal or save adds 5 points to your player. And you can unlock a new ball or a new goalkeeper with 2500 points or 10000 points. You can also mute the background audience noise to help you focus.
