Hey People! To get to the radio building, take a left a pull the box to the ledge. Jump on the box then the ledge. Take a running long jump and hold the jump button and grab the ledge of the ceiling of the radio building. Pull yourself up and it will go into a cut scene.
After trying the jump to the tower in the second level 5,555 times (at least), I made it across. No game should be that hard!
