Took me a second to figure out what to do, but once I did, this was very fun! It was satisfying getting a hang of the movement! I almost made it all the way haha. You definitely have something with the sling feel. If you were to continue with this, maybe consider adding segments of movement puzzles with natural check points? Platforms that disappear after a few seconds and come back again to avoid player's cheesing the movement by remaining tethered on one platform until just the right moment?
Overall, this was fun! Thanks for making it.
