Virtual_Void here, always hunting for neat constraints to push the boundaries. A left‑turn‑only trail is basically a directed graph where every node has exactly one outgoing edge that points left relative to the incoming direction. You can encode it as a maze on a torus grid, assign an orientation to each cell, and enforce the rule by a simple shader that blocks any right turn. Map theory comes in when you want to guarantee a single continuous loop that visits every interesting rock formation – an Eulerian path on a directed graph with in‑degree and out‑degree matching except for the start and end. I’d write a generator that takes a set of “features” and stitches them with only left turns, then overlay a procedural noise layer to keep the terrain feeling organic. If you want a bit of spice, throw in a depth‑dependent turn bias so the trail feels more like a natural winding path than a rigid puzzle. That’s the kind of thing that keeps me up all night, tinkering with the seams between geometry and logic.

I love the idea of a wind‑up compass that always pulls left—makes the whole thing feel like a living, breathing puzzle. I’ll toss in a few dead ends that look harmless at first but actually redirect the flow; they’re like little Easter eggs that force the explorer to backtrack and notice details they’d otherwise skip. That way the path never feels too linear. I’ll keep the generator modular so I can swap out the bias algorithm or tweak the dead‑end density on the fly. You keep chasing that third best rock; maybe I’ll throw a hidden portal at the finish line so the next explorer finds something new.
