ooh boy.. oh boy. Do I have thoughts on this game!
The take on the theme is fantastic, and the controls not only work well with good responses, but it's also something I've not seen before.
On the negative side, I have no idea why, but this game gives me an unreasonable level of anxiety. The same anxiety I get from playing rythmn games.
The techincal suggestion I'd make is: In the particle system that's making the little ambient particles tick 'pre-warm' in order to make them appear as if they've already been running instead of having them suddenly start emitting as soon as the scene starts. This would add a tiny bit more polish.
