One of the most original interpretations of the jam theme! The flying hand reminded me of the music video "Sad Machine".
I like the concept of flying through the OK-hands, and it was very satisfying to see the hands open up as I flew through them.
It was pretty hard though - it took me several attempts just to pass the first hand. After that, I got stuck on the fifth hand, couldn't get "my hand" low enough to pass it even if I brought the cursor to the bottom of the screen. It might have been better if the mouse cursor was invisible and at the hand's spot rather than as a separate entity below it.
What added to the frustration was the music restarting every few seconds (every time I lost). Other than that, the music, the choices of color and the basic feel of the game was quite calming.
