A challenging but fun game! It felt like I was moving too fast sometimes - but then again, you want it to be fast and snappy, so it's kind of a tricky balance to get right. It was quite hard (impossible?) to grapple onto things while falling, so missed out on that feeling of "phew! saved myself" as it always ended with me on the floor (skills issue, I know).
But it's a really cool movement mechanic and you've presented it well with good polish and visuals. Nice work!
