The force can levitate things, he is using the force to levitate himself. Its a bit of a stretch but not impossible. I mean he's not really flying, that would be stupid.
He is both balancing, levitating and throwing grenades. Bit of a strech went out the window some time ago. Now if he used the force to slow his descent so as to survive the fall. That would be good.
I was only responding to the "flying" bit. Holding himself up is definitely accomplishable, now doing other stuff at the same time....that is less believable.
There's no balance, he's standing on a platform as wide as he is. You're literally using TK to move a thing, you just happen to be standing on that thing. Didn't know use of arm was restricted to only when not using TK.
So you did not hold it still. Then it is moving. Yeah balance is needed. @Narsi sure but itvis not going to be steady not with out a lot of focuse. Idea get somthing as wide as you throw in to a swiming pool and stand on it.
Actually in canon we see Jedi and Sith having to use hands to help them using telekinesis. In Star Wars the clone wars, rebels and other media. Only darth Vader has been shown to not need to do that. But this is stupid and we should all just drop it since it won't get us anywhere
