Your Brain isn't Ready for har•mo•ny 3

har•mo•ny is a special kind of frustrating brain teaser that's actually quite enjoyable. The same goes for har•mo•ny 2, and at this point I think it's safe to assume that the recently announced har•mo•ny 3 will also follow suit. har•mo•ny 3 aims to ratchet up the difficulty with 90 new levels, "morphing color palettes," and some additional challenges. It's also going to include new music from Hammock (6 new tracks, actually), which will only be available in the game.

If you're interested in some mellow (and melodic) puzzles that will also drive you up the wall, you can check out har•mo•ny 3 when it releases later this month.
