The grapple has been one of the more difficult mechanics for us to teach because of its dual behavior:
When grappling using only [M2], the player is yanked in a straight line to the target
When grappling using [M2] while holding [Shift], the player swings in an arc around their target.
The second option is the best way to smoothly recover from under platforms, but it is also one of the most difficult mechanics for us to teach, since the concept of the grapple being able to behave in two different ways is unintuitive for a lot of players.
I'm glad that you checked out the tutorial and gave us this feedback. It's really important to us to know which mechanics our tutorial teaches effectively and where we are falling short.
Thanks for your feedback and we encourage you to check the Alpha build on our Discord if you haven't already!
