The only issues I had is that sometimes the dash would not trigger, which caused me some falls into pits haha. this prominently seemed to happen when I would jump form a ledge and try to activate the dash right away.
and the grapple felt like the mouse position needed to be a little too precise? Like it seemed if I didn't have my mouse right over the grapple point (or perfectly lined up in the direction of it, if its a raycast) when I clicked, it wouldn't connect and I would fall. Though like I said, this may be a skill issue of my own haha, and a design choice for you :)
