Sad armadillo is sad because he can't fly like the birds. He can run and roll, though, and with your help, he can do something remarkably close to flying! Dillo Hills by Fex Labs is a browser-based action arcade game similar to the iPhone release Tiny Wings. All you do in this simple physics-centric title is hold the [down] arrow key to dive towards the hills. When you hit terra firma you start to roll, coasting along the slopes to gain more and more speed. Release the button and soar high into the sky, picking up speed and traveling to distant lands in the process!
Happiness is equivalent to hang time in Dillo Hills, so naturally you'll want to stay in the air as long as you can to keep your 'dillo smiling and content. Happy armadillos move faster, too, so the more speed you have, the more speed you'll get, the higher jumps you'll make, etc. Smacking into the ground at an awkward angle makes 'dillo unhappy, so try not to do that, k? Keep your speed up and your airtime high and you'll eventually cross to new zones, featuring more birds to smack into, more gems to collect, and tougher hills to traverse.
Oh, and wait, what's this? Unlockables? Tons of them? Yup, you know it! Collecting diamonds from the slopes allows you to purchase ability upgrades in the shop available from the main menu. Simply click your way to the store and you can increase your drop speed, decrease damage taken, and more. You can also choose different non-armadillo characters to play as, including a turtle, a squirrel, and a penguin! You can even unlock a few hats to spiffy up your dress for your romp across the fields!
Dillo Hills doesn't innovate on any front, but it does provide a genuinely good browser gaming experience. Play it for the cute animals. Play it for the intense hill-sliding action. Play it because no matter how many times you try, you just can't get the drop timing down perfectly. Or, just play it because you can make a penguin wear a top hat.
