When jumping, pressing the jump button again fast enough produces a double jump effect

When looking directly down or directly upwards, holding keys that should move the player diagonally instead move the player to the left or the right.

Remove the pre-fire "mechanic" from the hook

When jumping (in place??), boosting shortly after being in the air automatically makes the player jump again when the player hits the ground if it the jump button is held down.

When jumping into a wall from directly touching it (or hooking it and reeling in until the player is touching it) then boosting, it will hold the player in place on the wall

On top of the giant walls, gravity is distorted

When tethered to a wall, the hook will lower the player slowly.

Making sure feet properly reach the ground (for unbalanced land such as stairs).
