Doorbell
A tool that creates a 1.5m x 3m x 0.5m doorway centered on your aim point in any surface. Just walk on in! Press "C" to switch to Tunnel Mode, then hold LMB as long as you want to keep carving deeper. In Tunnel mode, press "N" to switch off the smart mode and just dig a tunnel straight ahead from your position. Subtask worker object management derived from My Cresta’s Exploding Stars mod.
