Had a lot of fun playing this one!
In terms of design I love the laser, it's a nice spanner in the works that makes the game a lot more interesting because now there's also something you need to avoid with the the tether, rather than wanting to catch everything. I'd love to see some sort of reward for catching the missiles, e.g. every missile caught instead of dodged would give like a tiny amount of energy back or something, I think it would make it extra satisfying (though obviously that would affect balance)
Really impressive art and music too!
(p.s. my high score is 92)
