Hey thank you for taking a look at it and giving me some feedback, I really appreciate it!
I never thought about the catwalk issue but it's an easy fix, I'll take a look at it.
The ability to plant in the truck I thought was a fun thing to do, wasn't sure about it but yeah, it's probably too much.
Finally, I think you might be right about the underground passage, because initially there was no fast and safe way for Ts to rotate from A to B because mid was too big, but that might not be the case anymore so I'll seriously think about removing it.
