From the README

A 3D vector tower-defense on a spinnable cube. Runners enter on the bottom face and path across the surface toward the home Core on the top face. Every face is a 9×9 grid of identical cells; you place turrets to build a maze (turrets are walls — you can never fully seal the path) and to shoot runners that share a face with them.

Pure vanilla JS + Canvas — no dependencies, no build step. Art is the "Hexforge" look: sci-fi machinery + steampunk clockwork lit by Arcane-style hextech glow.
