I feel like I'm missing something really simple here, but I can't find anything about how to actually pull boxes around. I've seen on videos where the "push" arrow turns pointed down for pulling, but I can't for the life of me make that happen. Please take pity on an old gamer and tell me what I'm missing.

It's been a while since I played this game, but if memory serves me correctly, and I'm not sure it does (being an older gamer as well) when you find a crate that the curser points down you can pull that crate. It looks like the curser that you see to push. Let me know if that helps.

I got back into the game and I can conform that you can pull boxes. But they have to have a metal handle across the middle. If it does you can push, with the curser pointing up, and pull it with the curser pointing down with it on the strap.

That's the bit I was missing. Thanks!

Your welcome and no problem. We older gamers have to stick together.
