I don't seem to understand what the goal of each level is... But I don't care! It was fun enough to move the drone around and blow leaves and making sounds. It's a shame that the game abruptly ends when you lose, specially when you don't understand the lose conditions.
There's some technical issues but not major. When I lost and retried, the sound stopped and the game lagged a lot, eventually freezing.
In my opinion the game would have worked as a fly-a-drone toy without any goals at all. It was quite enjoyable!
