It's not that the controls are loose because they are pretty nicely tuned. The problem is the momentum in the game, and how different it is with meatboy on the ground and in the air. On the ground meatboy sticks to everything like... well, a wad of meat, which is good because it makes sense. When meatboy goes airborne it feels like he might as well have wings. Any twitch in one direction or another will send him flying way too hard, which is bad because he is a wad of meat. Neither a wad of feathers nor a winged wad of meat.
