Hi, thanks for playing my game. When the first big guy makes his appearance, he punches the wooden boxes out of the way the two big trolleys open out. You should be able to walk through in-between the two big trolley things. (the fallen wooden boxes don't collide with the player). Maybe I need to put a flashing arrow to make it clearer.   If not then its probably a bug and I'll need look into fixing. thanks for the feedback.
