Bitplanes

Bitplanes in a Sokoban Level Solver

I've been building a Sokoban editor and solver for tilebasedworlds.com — a side project for tile-based puzzle tools. The solver ships entirely in the browser as a WASM binary, which meant the first real question was not "how do I implement A*?" but "how do I represent a level?" That choice turns out to propagate through every part of the solver, the URL format, and the state-space design. The answer I landed on was bitplanes.
