Huge props for adding a sensitivity slider.
This is an awesome mechanic that has so much potential. Its all the fun of Zelda's hookshot but with an added "reverse" hookshot. I would have loved to see a more platformer / adventure style map, rather than just a wave shooter arena, because a feel like this mechanic is all about movement, and I wished I could have utilized it to navigate around a large map. Even still, launching myself up in the air and taking out enemies as I was falling was a lot of fun.
I really enjoyed the simplistic controls (reminded my of Portal in that way), and the intuitive blue / red markers to let you know if you're in range.
Great work.
