What's the difference between EDGE Classic and Extended?

I purchased the Android Humble Bundle and there are two different versions for EDGE that I can download/install, the "Classic" version (23.2 MB) and the "Extended" (23.1 MB). What is the difference?


Solution 1:

The levels are different. Classic has 48 classic difficulty levels and 16 hard levels. Extended has 48 extra levels. Seems like Extended is kind of like DLC to the first game. I haven't unlocked all of the levels for either yet, but I do have them both installed.
