Maybe I'm bad, but the player control, mainly the grapple mechanic is a bit irritating to be honest LOL. Like you can swing, nice, but if you hit a wall it would cancel and you'll fall to the spikes. Then it's so fast that it's really hard to calculate the trajectory because if you let go 10 milliseconds too early or too late you'll miss.
Despite that, the art is nice and the elements are there, so good entry for the jam!
