The idea is really cool and it needs some skill ! I think the character is little bit to floaty, even with the break. It's sometimes complicated to go where you want to go because your character is flying in an almost uncontrollable way.
It needs more feedback too, for example something that tells you what you can grapple and what not at what time, I died many times because I wasn't able to grapple for whatever reasons.
But overhaul, The game can be something really interesting, the art style works very well with the gameplay. Good job for 48 hours !
