Really mesmerizing! I've actually been watching Hypermasher from time to time since it was also submitted here [1]. I like the improvements that you've made, the interface is certainly nicer, and your codebase appears to be more concise. Hypermasher could run without Flash (barring the music), but Hyperlax refuses to start without it, however that's just a nitpick (though you might be surprised at the number of people who have flash disabled by default these days.)
