So its for the cars, Can we get a setting that adds a small wooden trailer to all the cars?

I have two steam accounts, mine and my brother's and I bought the game on my account and he's playing it on my account. How do I transfer the save to his account? Thanks

When the game first came out, I played it on my macbook, and got through most of the game and even had a world record on a level. I just recently got my first PC and wanted to revisit this game, but no matter what i try I cant get my old save to appear on my new PC. I know there was a big physics change at some point (bunch of my records gone and most of my saved bridges on the mac break instantly now lol), but idk if that could be the issue. They're both on the most recent update, I have steam cloud sync...

can make publishing campaign be easier?

I don't have a lot of money and I'm just wondering is 3 really that much better than 2? Also 2 is on sale for $3 and 3 is on sale for $12
