I think this game has some big potential for creating amazing-feeling movement! Already, the speed and momentum, and especially the grappling hook feel really good to use, even more-so coupled with the very weighty, chunky sound effects. The mechanics were interesting too, and gave a nice layer of extra depth.
I do think that the main area of improvement would be to either pivot away from the more precise, small movement areas (like more towards a Sonic type level design where you just want to go fast and do more big grapple swings and jumps) or tighten up the controls for moving in tight spaces. At the moment, your momentum carries you a little too much even with a small tap of the movement keys, making things feel too floaty in those sections where you have to do tight wall jumps or things like that.
All in all, when the game/levels allowed it, everything flowed super well together and felt great to play. I would love to play a version of this with even tighter movement as well!
