From the TS blog:
Glitch HQ just received some substantial updates on iPhone, and Android release is in progress now. For this new version (1.3), we’ve revamped the interface, added mail and achievements, and added support for imagination and snaps.
...
Achievements: Completionists, rejoice. Ever wondered how close you were to earning all the achievements in Glitch? We’ve added support for achievements, filterable by category.
Really?!?!
We can see how close we are to getting an achievement?! Really? You mean it? Quick, quick, someone with an iPhone, can you confirm this? Please!
Don't tease me on this one, TS.
