EXCELLENT game, but really hits "DIFFICULTY WALL" after an early point

Added: still no update yet? ( though I notice the other title was updated ) This is still one of the best defense titles, why not make another level pack?

Before:
This is one of the best, and a fairly unique tower defense title.

but
I stopped playing it after the "easy" levels because it just becomes IMPOSSIBLE in terms of frustration.
(and the calm computer voice mocking you "...5, 4, 3, 2, 1 0." doesnt help.

( I have beaten other "defense" titles entirely, so am an not a total novice to this genre.)

Lets not even think about what the "hard" mode must be like!

I bought the one level pack, and it offers mainly more frustrating defeat ;-)

How about more levels of a TRUE "mid range" difficulty?
And / or some selectable adjustment for existing levels.
Perhaps some new unit types?

I really DID enjoy playing the early levels.

Please expand this great (yet impossible) app with more features!
( And iPad res would look great, Im sure.)
