Harmony 3 ($2.99) from BorderLeap came out not too long ago, but if you’re looking for more puzzles to play in this stylish game that combines color-based puzzles with soothing atmospheric music soundtracks, you’re in luck. Chapter 4, entitled “Endurance," has just been added to the game. These bring 30 new levels that bring the total in the game to 120. Oh, and BorderLeap promises that these are probably the hardest levels in the entire series so far. So, good luck with that!

Here’s a look at what awaits you in the new level pack:

Along with the new levels comes 5 new tracks by Hammock to enjoy while playing. Plus, if you haven’t picked this one up yet, you can do so for a $0.99 sale price. Huzzah! BorderLeap also recently updated their word game Alpha Omega (Free) also recently got a big update adding a bunch of new level packs and music, so BorderLeap is definitely not resting on their laurels when it comes to updating their games.
