The "Tele-Walk" checkbox has been added to the GUI, along with a Tele-Walk keybind. If enabled, the movement speed hack will also adjust your height in the direction your camera is facing, allowing you to run into the air like superman/woman.
The X/Y/Z-Warp keybinds have been changed to permanently move your character. In this way, the Y-Warp keybind now functions exactly like the old Time to Fly hack; i.e., it teleports you up or down while holding the key.
I have a made a new video showcasing how these hacks work if you are confused or would like to see what they can do.
I did not notice any issues with Time to Fly not adjusting your height.
Updating to version 56 is necessary for these changes.
