Have gold on levels 1-29. Get all stars and kill all the baddies on level 30, but doesn't seem to award gold or save progress (and no badge). Screen appears to hang after completing last level as well; takes it a while to "un-freeze". Have done a few times, restarted browser, etc, with same result.
if you don't click 'next level' after completing a level, but instead go to the main menu, you then have to do that same level again to be able to go to the next level (ie, can't pick the next level from the level selection screen)
