Would be great if not so many bugs... Once, my charachter was unable to jumb (don't no why), and the other one, unable to push the second rock in the jeep.
I give a look on the walkthrough to be sure and definitively, it's a bug, i did exactly the same... So I'm stuck and I'm not gonna try a third time... (And "save" could be a really help in this case)
But nice job anyway
