Shadow Generations - Tokyo Act 1 Mission 2 in
Liked running this one more than the main level, no minute of cutscenes
Pacing wise it feels akin to a Cyberspace level, it's shorter but feels like it has fairly high intensity through most of its run time and doesn't feel like it ends before it gets started. There's also a larger emphasis on 3D movement here, such as landing on the boxes to lower a pulley to air boost directly towards a wall boost pad, or the block maneuvering near the end.
The air boost to the bus in the last area gave me the most grief funnily enough, it's actually pretty tight due to how long your controls are locked
