After you add a point system and optional Facebook scoreboard for users, you'll create a
dynamic leveling system with a few code modifications, so users play harder and faster as
their skills improve. Then, you'll place the cherry on top of Canvas Ricochet with opening

First up is tracking score and levels.
6.4.1. Tracking score and levels
When we were about 10 years old (okay, maybe some of us were older!), we played Break-
out all the time. One of us played on the now-ancient Atari gaming system; another played
at Pizza Hut every Friday. We'd play over and over to keep raising our scores. Back then,
