This looks really fun. If there are skills that allow for a lot of maneuverability like dashes, air dashes, etc. that are on reasonable cooldowns, then that'll make things even better.
I do wish the boss battles they showed off had vertical elements to them though. Considering that that grappling hook thing will be a prominent mechanic, I was hoping to see arenas where you'll be zipping around all over the place instead of fighting on a flat plane. Will definitely keep an eye on this though.
