Sandbox 1: 6sec and 4 nanosec lets go!
actually Im stuck as well, i have beaten every lvl except sanbox 2 bro D;
if it is that your not getting bounced in the right direction off the yellow pad it might be because you aren't crouching =)
you can find a shotgun in the parkor section
my current best time on sandbox 2 is 22:34:17
