Seems like there is also a homing kick attack. Press y when locked on to kick an enemy into whatever is behind it. You have to use this on enemies that block homing / jumps, or just for chaining enemies you might not have had the chance to homing chain.
Kinda reminds me of something he'd do in the OVA.
EDIT: Seriously, hanging onto ledges and wallrunning at will is about the same caliber of usefulness as Samus getting a wall grab in Fusion/Zero-Mission. That is not an understatement, especially for those used to playing 3D sonic games, and accidentally going too fast of a platform / having trouble backtracking.
