Really cool concept for the controls, and different from anything I've played before. Some indication of power on the jump would be nice (e.g. a gauge showing how far off max-power you are).
Because they're so different from other games, the controls are tough to get your head around, which makes the pace quite slow and even some basic platforming areas quite tough. I'd love to play more of this, but I'd definitely need easier levels to get used to the controls.
Really liked it.
