Two apps have been released into the Windows Phone Store that will raise the profile of its application collection, and likely give users of the mobile platform something to smile: Angry Birds, the ‘Space’ edition, and Cut The Rope, are now available, The Next Web reports.

Angry Birds Space will set users back a mere $0.99, as will Cut The Rope. The titles feature 150, and 300 levels respectively.

Windows Phone’s Store is chock full of applications, sporting more than 120,000. However, the platform has long suffered from a lack of ‘top tier’ applications – those that could be deemed as ‘must haves.’

App density, the average quality of higher end applications present in a single marketplace, is non-numeric metric that is a key element of user experience, TNW says.
