Nice entry! Always a fan of digging games. I liked the oppressive atmosphere.
Considering how large the map is you had to hope for good rng for the wurm's pathing. Unless there was some logic behind it? I didn't see the slowing turrets having any effect. Maybe I was too focused on digging and preparing to dodge out of the way.
The only thing I think was missing was canceling your action, to avoid long pathing and hoping you're not gonna get eaten.
Good job!
