Research direction

Open the linked CodeSandbox in Chrome and reproduce the freeze by uncommenting the for...of loop in js/game.js inside initGame(). Check whether the failure consistently depends on 64 iterations and console.log calls; done means identifying the cause and confirming that the sandbox no longer freezes or crashes for this case.
