As other have already said, this is a superbly polished game for a 48 hour jam. It's the little things, I noticed, like how the tether felt like it had real tension in it, how that tether could be broken, but how the game would also preserve the tether under certain circumstances, like while falling or when hitting a checkpoint. You managed to get through a lot of good puzzle design in such a short game as well. High marks overall; you've left me with very little to critique!
