Approved!
The map is OK, it's well-built and well-thought, however, and once more time, the creeps' drops are not balanced.
For example, two level 3 units drop nothing while 2 felguards (lvl 2) drop a lvl 2 power up?
I don't think you made a good use of textures in this one.
My rating is 3/5 (Useful).
