It seems to be quite buggy if you have fast tower enabled and no blocks available to place. If you have no blocks at all in your hotbar you seem to be prevented from jumping when you stand still and it tries to tower up, while if you do have blocks in your hotbar but you have autoswitch disabled and you arent holding a stack, you go up but dont place any blocks at all. It would also be nice to have a speed setting for fast tower.

@Wide-Cat I've fixed the bugs you describe and added a setting to control the speed of the fast-tower.
