Going head first into this Ludum Dare! Anxious to see if I can actually pump something out in 48 hours…

Tools:Unity
Flash CS 6 (I use it for making sprites)
Spine (skeletal animation software)
Audacity

The query:

Is a free 2d framework that manages sprites such as Orthello allowed in the Compo?
What about a 2d framework that is not free such as 2d Toolkit?
Thanks and hope we all have some funnn.
