Diodes: Intended!
Overhead: Intended!
At the Pond: Intended! Yeah, I'll keep 3 batters for lenience. The core trick is to turn with batters near the exit.
African Wigwam: Intended! Yeah, the batter is precise. I consider it OK because it's immediately at start, and almost everything else fails, pointing to this batting idea.
Jerboa Garden: You took great care to delay the second digger, giving the builder enough time to climb the second digger's left wall and bonk at the top. I didn't think this timing was possible. This will be hard to fix, but I should fix it. You're very close to the intended solution:
After the second digger is halfway through, assign her miner. This will delay her breakthrough, allowing the builder to climb and bonk.
