Chalkline#029

Description

Draw towers and maze walls freehand with chalk on a giant blackboard; the chalk erases over time, so your fortress must be continuously redrawn, and dust clouds choke enemies in thick strokes. Signature: erase an enemy's favorite shortcut with one swipe.

Blackboard slate-green, white and pastel chalk textures, hand-drawn doodles, chalk dust motes.
