If at the very end of the level, instead of running ahead of the boulder and bullwhipping across the chasm and then bullwhipping up and letting the boulder go under, what you do is wait for the block to fall away, then edge back and hang over the edge under the ramp, and let the boulder go by, then you can run BEHIND it.

It takes a little timing, you hang just until the rumbling starts then climb up as the boulder goes over. Wait too long and you fall, go to early and you get crushed.

The problem is, then the boulder crashes out to daylight and the game HANGS because Indy is in the wrong place for the "end of the level" cut scene.

Tsk tsk pretty slack play testing if you ask me!!
