Loved the intro! And I liked that the car physics were a little wonky, and as a result using the crane arm essentially became part of the movement - really enjoyed trying to coordinate driving and manipulating the crane arm at the same time (I was NOT good at it).
I think I may have bugged out the barrels? I got as far as trying to use one to push the button on the wall, but each time I picked one up they vanished - perhaps I got them below the level when I flipped the car or something? The crane hook was still green.
Anyways, very cool, had fun with it!
