Really neat concept! The use of the limitation is also very clear.
I had a bit of a hard time understanding how the game worked at the start, but after a couple of attempts, I managed to figure it out. I also don't know if it's a WebGL issue, but my aim felt very swingy and laggy at times, which made aiming quite difficult.
Other than that, the visuals look nice and the art is very cohesive!
