I love grapple mechanics in games, I'm really happy to see you embracing them for this jam! Being able to change the player's gravity is really cool too, but it can feel overpowering at times. Consuming a lot of air when you have forward momentum pretty much guarantees that the player will be able to reach the end since there isn't really anything stopping him from just flying above the whole level. I always enjoy seeing other people's takes on first person movement games, and this one was super creative!
