Wall Crawlers

Walls used to be enough. Not anymore.

Wall Crawlers adds the Climber — an undead woodworker that doesn't stop at the bottom of your
wall. When it can't walk to you, it builds a ladder and climbs. Box yourself in, wall off your
base, dig into a hillside — if there's a wall between you and the Climber, it'll scale it and drop
in after you.

How it works

• The Climber is a zombie-like mob (it chases, burns in daylight, the usual) with one extra
  trick: when its path to you is blocked by a wall, it lays down temporary ladders and rides
  them up and over.
• It actually reaches you. It will climb the wall around your base or scale the lip of the cave
  you're hiding in. Simple walls no longer keep it out.
• The ladders rot away. Every ladder it places removes itself after a few minutes, so your base
  never ends up permanently scaffolded — the siege cleans up after itself.
• Light on performance. No constant world scans and no per-ladder ticking entities — the climb
  logic only runs when a Climber is genuinely stuck against a wall, so it won't drag your game down.
