Simple but challenging game.

HARD mode:

The screen is divided into two halves. You move the ball on the right, and the one on the left will follow your movements. The challenge is to hold as much time as possible without touching the geometric figures that move through the left area.

HARDEST mode:

Same as the previous one but in this case the ball on the left inverts the movements both vertically and horizontally.

How long will you be able to endure?
