I gotta say the player is a bit fast, other than that the music is pumpy, i liked it but it made me nervous a bit. The music felt like this game was a some sort of actşon game :D. I like the design of characters they're kinda general but they work good here.
As for the game design, i like the brown box idea maybe you can add more stuff that drone can interact with. And maybe making drone transparent for the red and blue walls might be a good idea.
Solid gamejam game at least 3,5/5. Good job!
