This is a rough one to be honest. The visuals are absolutely stunning and it's a shame there's no category for that, because you would rock it.
The gameplay itself on the other hand didn't really work for me. The voice really put me out of the game and controls were hard. If you plan to improve this ( which I think you really should ) consider using a more soothing voice and the option for subtitles at least. Also, to make it a more accesible, you could automate the drone partially, so the player can focus on one element, instead of two.
Overall, this result still feels impressive and considering your difficulties with webgl, it's awesome you were to submit this!
