I could not get past the spike traps in the clouds, your "freeze" ability has a bit of a short active time, and does not give you much leeway to not be exactly right.
The mechanic of maintaining your height and gliding across, I think is a cool concept and could be part of a fun game. I'm not sure if I'd enjoy a game with that being the only move.
The general movement feels decent, unless you are doing the freeze when it becomes a little jerky and un-responsive at quick time adjustments.
I think that freeze might not be the best name for the ability as when I first saw this I thought that my character would become an ice cube or do something along those lines.
