To add a note on CCD:
Dynamic objects always use a CCD when collision happen with Static Shapes.
This is why there is practically no chance your object pass through your level. Even if your walls are very thin.
But be careful since there is a minimum thickness size (differences between 0 and 0.01 will crash Box2D).
It's sounds like it's small but Box2d is tweak to work well between 0.1 and 10 Meters (KMS units).
Values are scaled thanks to Brucey (look at render.bmx).
