The gameplay is pretty and I liked the explosion effect. All the levels felt simple after I understood the controls. I think this could make a cool rhythm game if the drones moved to the beat and you had to tap them on the beat, and it would fit the title too.
Is the main menu audio is playing on the word “drone” (with the drawn out synth note)? If so, that’s kind of clever but I think something a bit more musical would fit better. Also, I think the last level’s music is a bit too loud/piercing.
Anyways, I can tell this took a lot of work to make and it’s high quality overall. Well done!
