I like the very interesting idea of using the drone in order to solve the puzzles. I am very surprised that you managed to implement a developer commentary mode in a short amount of time. The game looks great visually and looks polished. The SFX sound nice. The game is pretty simple to play.
I find it weird that the drone sometimes clips into the wall:
I wish that the small circle buttons also had a sound effect play.
But overall, great game!
