I like the physics handling of the drone, and how the movement is heavily altered once you're tethered onto the box. The time limit and level length is really tight though - I managed to beat it after 5 attempts, and only barely.
The graphics are quite nice. I think that the use of fewer colours adds to the charm. I like that the battery functions as the timer in the UI.
The music feels a little ominous. Were you aiming for a droning feeling?
It would be interesting to see more levels where the objects varied in the ways that they affect the drone's movements.
A fun little drone game.
