How embarrassing. When I updated the Emscripten build to use WASM, a major reason I bothered to do it at all was that I'd heard that WASM was capable of reallocating its memory arena larger on the fly. Turns out that it _can_, but only if you specifically set the option in Emscripten to allow it. With this option set, I can finish a 25x25 Galaxies, where previously the game would crash part way through (and not even a very large part) with errors about memory growth in the Javascript console.
