I've been messing with the Zephyr's Grip for a good while now, and I've noticed that it can be *very* inconsistent. Sometimes, it will launch you roughly in the direction you're pointing, as I assume is intended. Sometimes, it launches you straight up. Sometimes, it stops you dead in the air. Sometimes, it decides not to work at all.

I'm not sure what needs to be done to make it work more consistently, but maybe if the hook were faster, it would outspeed the player and work more consistently? It might also help if the hook matched your vertical velocity? I'm not sure, but I want some tweaks because it would genuinely be my favorite grappling hook if it just worked consistently.
