Here's quite the surprise: Beards & Beaks ($2.99) features downloadable content (DLC) i.e. extra levels and add ons that can be purchased from within the game itself.
Up to now, our games have been fairly limited, requiring a whole new download to bring new levels, like IloMilo. Now, developers evidently can start offering extra levels, new mini-games, etc. as an extension of the main game (as well as charge for it, hello!).
Luckily the "Forest Map" add on here for Beards & Beaks is completely free. What's more, it's mean this game can get extended life out of it since MSG can keep creating new levels and features.
Ah, the future of Windows Phone gaming is looking good. Grab the game here in the Marketplace.
