Pretty fun game. The switching of the shapes and lanes is a nice twist on the guitar hero. I would suggest two things for the controls. 1) Change the Shift to like space, because if you click shift too fast it actives sticky keys and knocks you out of the game. 2) Allow the player to go back to the previous shape because if you accidentally hit shift you gotta go through all the switches which cost you a score. Very minor changes, loved everything else. Great work! Keep it up!
