i like the idea, though the explanations could have been better, some UI to remind you of how you will fall could be great, and what the hell is happening with enemies ? sometimes they are in a place blocking more than half of the map and stop moving for so long, and the way they moving is hard to predict making it even harder to go to certain places sometimes. Maybe they should have the same gravity as you, could try make them only fall too, like they don't choose to move in some direction.
The concept is really original though
