When you see Eric go up ramps and there are no "checkpoints" there, just turn around. It savse a little time. Also, time usually runs out when you're grinding on the gate in the playground. When you get to the end jump off and manual.Put on Moon Gravity. get off your board into a combo run out. jump and get the "check point" in the air. Then, run down into the alley, and into the dumpster. the combo run out should just be running out. Caveman out of the dumpster into a manual and get the last "check point." This took me a while to get just right.
