Move, as written, does not discuss using the power on oneself. It is written from the point-of-view of affecting increasingly larger objects, in increasing numbers, with increasing dexterity, at increasing distances.
The key points in the write-up seem to be the Silhouette of the object, and the Range from the user. Silhouette begins at 0 (smaller than a person) and Range begins at Short.
None of this encourages nor prohibits the use of Move to affect oneself.
Flight and Levitation have appeared to varying degrees within the Expanded Universe/Legends, but do not appear per se (at least not that obviously) within the films. There are reasonable arguments, based solely on observation of a character's movement, for either the ability to or the lack of an ability to affect oneself with Move.
- Luke Skywalker falling after his confrontation with Darth Vader in Cloud City. Is this a use of Move, or is this a function of the shaft itself?
- Kenobi in The Phantom Menace rising up out of the shaft and over Darth Maul. Is this Enhance, or is this Move?
- Kenobi in Attack of the Clones swinging to safety on a cable after fighting with Jango Fett. Is this Enhance, or is it Move?
With no confirmation or refutation in the core rules regarding this, it falls to the GM and group to decide if this is something they wish to use the power to do.
The Force Powers and Narrative sidebar in Chapter 8: The Force, encourages a group to allow for creativity within the scope of the Powers as they are defined, providing that use supports and enhances play, without becoming a source of abuse.
If the group is uncomfortable or dissatisfied with the imagery and idea of a Force User manipulating their own form with Move, they do not need to allow it. Neither do they need to prohibit it because it is not specifically mentioned. It is up to them.
In the given example of falling a long distance, such as down a shaft or from a window, the Force User would not need to 'throw' themselves, but rather attempt to close the range between themselves and something to grab on to. In essence, as they are not grounded, they are pulling on the object without the Control Upgrade to remove it from its mounting, and so are drawn toward it instead of it toward them.
Falling rules would still apply, possibly mitigated by making an Athletics or Coordination check (Chapter 6: Conflict and Combat, Environmental Effects section, Falling). Making such a check well, perhaps with significant Advantage or Triumph, could influence how the scene is narrated, making room for a feature of the environment which enables the Force Sensitive to break their fall more safely.
