Thanks for the feedback, it means a lot.
I already made some adjustments to the movement that will be included in the next update:
-Jump reaches apex faster.
-Quick climbing ledges instead of just jumping up. (Only if there is a place to stand on)
(You can also just hold space as you grab it to immediately climb it)
-Dash can put you on top of a platform if you hit near the ledge.
When it comes to the grapple I'm still thinking, I was thinking either first attack from it dealing more damage or just a unique attack for it.
I personally find it useful to quickly close the gap to an enemy or a boss especially when stating it right at the end of the attack, but I will still think about it changing it a bit. I understand that it might feel like too much risk for to little reward.
If you have any more ideas I would love to hear them.
