If anyone is wondering why your character twitches when you jump,
open your Jump state, select the Jump Blendspace (BS1D_Jump), and in the “Details” panel, under “Settings”, make sure “Loop” is unchecked. 
Fantastic course by the way, thank you so much, @StuButler ! I really appreciated the intro to using Conduits and utilizing more advanced state machines to vary the jump starts and landings. For any beginners looking for more details on State Machines and “why” jumps are broken into 3 parts, this old but excellent series from Wes Bunn is also highly recommended: https://youtube.com/playlist?list=PLJH-vHPx6Bh-7BDR_ymPw_bwp886veq3O
