Great, except for bugs
Low rating because of the bugs.
Truly unique gameplay, makes it fun! Regarding the gameplay I do have to say, however, that it would be nice if it wasn't so hard to make the helicopter go DOWN. Sometimes I feel like I'm wrestling mightily just to let gravity take hold.
I played up to level 14. I struggled with that a few times--and now when I load the game and try to go to that level, I can't. The HUD at the top shows, but the rest of the screen is black. Please fix this so I can keep playing.
