very nice!
I liked the 3d graphics and the levels! I only played to 20% of the way through because I lost my patience with a level though.
Suggestions to fix up the few small problems in the game:
-have unlockable helicopters with different abilities for different levels
-add controls to rotate the helicopter on the spot
-tail should remain level when ascending
You might want to add some music and backgrounds as well. I thought it was funny how I saw my phone advertised in there too.
Other than that it's a very good game, almost, but not quite good enough for me to favourite. Just tweak those few things I mentioned and you have a winner. Maybe lighten up some of the levels a bit too. Some were very tight. Hey, a level editor and a different scoring system for online scoreboards would be cool too. Throw in a timer!
