Good news!
I'm working on updates to release after the gamejam.
Your idea of the walker knocking down trees is in the version I'll release after the gamejam.
It is called the "Mauler" and can only be installed on the initial "first" walker.
It automatically damages trees and rocks every 1 second, it takes 3 seconds to clear an object, each second the walker is stuck it'll still receive damage though, even with "Mauler" installed.
Thanks for the idea!
