Using both WASD and the Arrow Keys for movement was a good idea to respect the limitations.
I do like the concept of this little Police Drone climbing the tower for investigation - the mood between reading the display data and hearing the TVs felt a bit dreadful. Nearing the end I was worrying what I might find at the top...
As for sound effect, I found maybe making the drone wirr on each button press felt a bit loud? Maybe using different SFX for looking around and moving, or just toning down this wirr effect would work better.
Good entry nonetheless!
