Rainbogeddon is Nitrome's latest entry into their catalog of solid games, and holy crap, is it a barnburner. The title above basically says it all: it's an action-oriented take on the Pac-Man formula, where you'll actually have some sort of resistance to offer against the baddies as you're snatching up all the little dots to proceed to the next level.

You're going to need all the help you can get as well; as addictive as Rainbogeddon is, it also gets really damned hard. The variety of enemies can get a bit chaotic, and some of the power-ups can often have unintended consequences, but man, I just can't stop playing, and I'm not even a fan of Pac-Man. Try it out here for yourself.
