It's been awhile since we've seen ilomilo get an attention. In fact the premier launch game hasn't been touched since February when it received a hefty update, including a whole new story. The popular puzzle game is a great example of an original title for the platform, with great level design and a well executed UI (see our review). One could argue it's one of the best Xbox LIVE titles out there.
Unfortunately while version 1.2 does bring Mango support e.g. fast-app switching (perhaps 60 FPS), no new story was added nor any bells and whistles ala ringtones. In fact, we haven't seen any other changes, but like always we'll get a full changelog as soon as we can and let you know.
Anyways, for those who want it, you can grab the new version right here in the Marketplace. Thanks, Harry, for the tip!
