Would be better if the pulsing actually matched the rhythm. Pulsing does nothing but mess everything up, even going so far as to create deer-in-the-headlights by effectively blanking out the current obstacle if it's in contact with the middle, making it as if it's not there at all and leading to erroneous losses.
Also, wonky controls and unreliable hit detection lend to the game being less skill-oriented and more luck. I'd say about 80% of my good close-calls where more luck than good reflexes because of this.
Great music and concept, but I have to take a star each for these grievances.
