I like the idea of mixing Jump King style platforms and carrying things 1 by 1 to the predefined point (flashbacks from refueling car in Left4Dead 2) 

Two things that I would be a big win to me: 
1. Music: First, it gives the vibe of "I'm the speed," but in the long term, it becomes annoying—a mute button would be cool!
2. Camera: Smoothing or dead zones would make it more appealing for longer sessions.
