Don't be confused by this game!  Do the tutorial and it'll make perfect sense.  Think of it as playing with a bouncy ball in a box where you want to hit specific tiles on the bottom.  Your paddle is the grey transparent circle so be sure and keep it above the ball as it comes back.  Also, you'll notice small green lines on the edges which are there to help you gauge how high or low the ball is. 

It's nice to see a game that really comes out of nowhere with something fun.  This is a great variation on the traditional brickles game.
