Aha, nicely done. Very much enjoyed it!
I do have some constructive advice (Friendly advice of course).
I didn't read it anywhere else, but I was a little confused at the start, I couldn't get the hang of it at first, maybe a tutorial or something? I think it be mighty helpful!
I also LOVED the laser beams, I was turning them on and off, just to enjoy the good animations of them shooting
I'd say you've done a very good job on it. Maybe improve it a bit in the way of intuitiveness, and it would be much more helpful
Well done though, looking forward to what else comes from you.
