Every active power-up now shows as a slim ring on the worm's head that drains as it wears off: green when it's helping, red when it's not. It's on every worm, so you can read what you (and everyone around you) are running, and how long it lasts, without taking your eyes off the action. The old head blinks and shape swaps are gone, the rings tell the whole story now. Drunk bubbles stay, because they're too much fun.
